switch

The men of the maamad fasted on four days of that week, from Monday to Thursday; they did not fast on Friday out of respect for Shabbat or on Sunday in order not to switch from the rest and delight [of Shabbat] to weariness and fasting and [thereby] die. On Sunday [they read], “In the beginning,” and, “Let there be a firmament;” On Monday, “Let there be a firmament,” and, “Let the waters be gathered together;” On Tuesday, “Let the waters be gathered together,” and, “Let there be lights;” On Wednesday, “Let there be lights,” and, “Let the waters swarm;” On Thursday, “Let the waters swarm,” and, “Let the earth bring forth;” On Friday, “Let the earth bring forth,” and, “And the heavens [and the earth] were completed.” For a long section two people read and for a short section one person. [This is how they would read] at Shacharit and Mussaf. And at minhah they assemble and read the section by heart, as they recite the Shema. On Friday at minhah they did not assemble out of respect for Shabbat.

MISHNAH: He who gives to the innkeeper’s wife, tithes what he gives her and what he takes from her because she is suspected to switch. Rebbi Yose said, we are not responsible for the dishonest; he tithes only what he receives from her.

MISHNAH: He who gives to his mother-in-law tithes what he gives to her and what he receives from her because she is suspect to switch spoiled food. Rebbi Jehudah says, she wants to put her daughter in a good light and is ashamed before her son-in-law. Rebbi Jehudah agrees that if he gives to his mother-in-law in the Sabbatical year she is not suspect of switching to feed her daughter from Sabbatical produce.

Rav said they are forbidden and practice follows him who forbids. Why does he not say one follows Rebbi Eliezer. There are Tannaïm who switch their statements.

“The potter may sell”. Should we not worry and say, maybe he will switch? Rebbi Jonah said, one recognizes, these are for wine and those for oil. Rebbi Ulla said, the material of these is known and the material of those is known.

HALAKHAH: “If someone sows heave in error it should be ploughed under;” etc. Would it not be reasonable to switch? They fined him that his field should be worthless under the heave.

Some Tannaïm switch statements to combine gift with gift.

It was stated: But he may walk on it until he reaches the entrance of his courtyard. Rebbi Aḥa and Rebbi Zeˋira were walking on the highway. The sandal of Rebbi Aḥa was torn. When they came to the city gate, Rebbi Zeˋira told him, that is the entrance of your courtyard. Rebbi Aḥa wound a fiber around. Rebbi Abbahu wound a bundle of Jew’s mallow. Rebbi Abbahu was of the opinion that a bundle of Jew’s mallow is ready to be used. Rebbi Jonah threw them away before the fried food [store]. That is little honor. The honor of Rebbi Eleazar obliged him to take it off. Rebbi Jeremiah asked before Rebbi Zeˋira: May one switch? He said to him, it is permitted. Nevertheless, he told him: go and look for an Elder and rely on him. He went out and found Rebbi Abba bar Mamal, asked him, and he permitted. Rebbi Yose said, the Mishnah said that this is a kind of clothing: “Or with a left [foot sandal] on the right [foot], the ḥaliṣah is valid.” That means, in (length). But in (width) it must cover most of the foot.

There are Tannaim who switch. Rebbi Ḥananiah in the name of Rebbi Joḥanan as our Mishnah. Rebbi Samuel, Rebbi Abbahu in the name of Rebbi Joḥanan, anything which heals is not forbidden because of ways of the Emorite. “דרגי דרגיבת because of ways of the Emorite; Rebbi Jehudah says because of the idol Dagon, and Dagon’s head and his two hands. דונו דני because of ways of the Emorite; Rebbi Jehudah says because of the idol Dan, they say, by the life of your god Dan. No no, because of ways of the Emorite; Rebbi Jehudah says because idolatry, they say no God, turn away from us, we have no desire to know Your ways.”

Tearing applies to textiles and cutting to hides. Tearing in the middle and cutting from the sides. There are some who switch, tearing of hides and cutting of textiles. Tearing of hides, those soft ones, and cutting of textiles, felt.

The Torah said, lots. Lots made of anything. I could think that he should put two lots on one and two lots on the other, the verse says, lots, one lot for the Eternal and one lot for Azazel. I could think that he should give the Eternal’s and Azazel’s on one and the Eternal’s and Azazel’s on the other, the verse says, lot. Is that not the previous argument? It should be so: I could think that after he gave the Eternal’s on the Eternal’s and Azazel’s on Azazel’s, he could go back and switch, the verse says, one lot for the Eternal, there is only one for the Eternal, and one lot for Azazel, there is only one for Azazel.

What is the status of motion by an Non-Cohen? Ḥizqiah said, motion by a Non-Cohen is qualified. Rebbi Yannai said, motion by a Non-Cohen is disqualified. A Mishnah disagrees with Rebbi Yannai: “If he received with his right hand and put it in his left hand, he shall return it to his right hand.” Is his left hand not like a Non-Cohen? Explain it if his left hand was towards the inside. Rebbi Abba said, even if you are saying, towards the outside, there is a difference between motion by a Non-Cohen and one which is automatic. Rebbi Zeˋira said, they did not consider a movement of his hand as motion. A Mishnah disagrees with Rebbi Yannai: “If from the vessel something was spilled on the floor and he collected it, it is qualified.” Rebbi Bevai said, explain it if it was rolling towards the inside. Rebbi Abba said, even if you are saying towards the outside, there is a difference between motion by a Non-Cohen and one which is automatic. Rebbi Zeˋira said, they did consider a movement of his hand as motion. The Mishnah disagrees with Rebbi Yannai: “He took the fire-pan into his right hand and the cup in his left.” There is a difference because he cannot do it otherwise. Should he hang it on his arm? It is not respectful. May he switch? They wanted to say, if he switched it was disqualified. Should he lower it? If he lowered it from his right hand to his left hand it is qualified. Could we say that also there, let him lower it? There if he lowered it it is disqualified. [If he switched it is disqualified.] But here if he lowered it it is qualified; if he switched it is disqualified.

HALAKHAH: “There are four New Year’s Days,” etc. It is written, this month shall be for you the head of the months. For you it is the head of the months but it is head neither for years nor for Sabbatical periods nor for Jubilees nor for planting nor for vegetables. And I could say, for you it is the head of the months but it is head neither for kings nor for holidays. Rebbi Jacob bar Aḥa, Rebbi Yasa in the name of Rebbi Joḥanan: It is written, he started to build in the second month, in the second, in the fourth year of his reign. It bracketed the fourth year of his reign with the second of the months. Since the second of the months is only counted from Nisan, also the second in the fourth year of his reign is only counted from Nisan. Or is it only the second in the month? Any place where the second day in the month is intended it is explicit. Or is it only the second in the week? We do not find this count in the Torah. But is it not written, it was evening and it was morning, the second day? One makes no inferences from the Creation of the World. Which one is the second of the months and which one is the second of the years? Rebbi Ḥanania and Rebbi Mana. One said, he started to build in the second month, that is the second of the months; in the second, that is the second in the year. But the other one, even if you switch it does not change anything. Rebbi Simeon bar Karsana in the name of Rebbi Aḥa understood it from the following: This month is for you, an exclusion. The first it be for you, [an exclusion.] An exclusion after an exclusion is to include for kings and holidays. Could one include for years, or for Sabbatical periods, or for Jubilees, or for planting, or for vegetables? Following what Rebbi Jacob bar Aḥa, Rebbi Yasa in the name of Rebbi Joḥanan said: It is written, he started to build in the second month, in the second, in the fourth year of his reign. It bracketed the fourth year of his reign with the second of the months. Since the second of the months is only counted from Nisan, also the second in the fourth year of his reign is only counted from Nisan. Rebbi Jonah, Rebbi Isaac bar Naḥman in the name of Rebbi Ḥiyya bar Joseph: He started to build in the second month, that is the second of the months; in the second, that is the second in the year. And when he says, in the fourth year of his reign, it bracketed the fourth year of his reign with the second of the months. Since the second of the months is only counted from Nisan, also the second in the fourth year of his reign is only counted from Nisan. Samuel stated and disagreed: In the third month of the Israelites’ exodus from Egypt. From here that one counts months from the exodus from Egypt. Not only months, from where years? The Eternal spoke to Moses in the wilderness of Sinai in the second year. Not only at that time, from where later? In the fortieth year of the Israelites’ exodus from Egypt. Not only temporarily, from where for later generations? It was in the 480th year of the Israelites’ exodus from Egypt, etc. After the Temple had been built they started to count from its building: It was at the end of twenty years after Salomon built the two houses. They did not merit to count from its building, they started counting from its destruction: In the twenty-fifth year of our exile, on New Year’s Day, on the tenth of the month, etc. They did not merit to count for themselves, they started counting regnal years, [as it is written,] in year two of Darius; in year three of Cyrus, king of Persia. And I am saying, he started to build in the second month, in the second, in the fourth year of his reign. It bracketed the fourth year of his reign with the second of the months. Since the second of the months is only counted from Nisan, also the second in the fourth year of his reign is only counted from Nisan.

Rav said, I am saying not less than the volume of an olive. Does this not disagree with Rebbi Joḥanan, since Rebbi Joḥanan said, for me and for him who did not make eruv? A baraita supports Rebbi Joḥanan: An eruv needs a measure neither at the start nor at the end. “On a holiday which falls on a Friday one makes eruv neither for courtyards nor for domains, the words of Rebbi Meïr. But the Sages are saying, one makes eruv for courtyards but does not make eruv for domains”. One makes eruv for courtyards, because it allows something which is allowed to him, but does not make eruv for domains, because you would permit him something which is prohibited to him. There are Tannaim who switch. Rebbi Eleazar said, since there are Tannaim who switch, we have to take notice. Rebbi Jeremiah in the name of Rebbi Ze`ura: He who wants to do it right makes the eruv the day before. Rebbi Yudan said, what you are saying is when he did not make eruv tavshilin, but if he made eruv tavshilin it is permitted. Rebbi Yose ben Rebbi Abun asked, does eruv tavshilin permit dividers?

HALAKHAH: The Mishnah is Rebbi Meïr’s, as it was stated, “what is the time of rainfall? Rebbi Meïr says, the early one on the Third, the average one on the Seventh, and the late one on the Seventeenth. Rebbi Jehudah says, the early one on the Seventh, the average on on the Seventeenth, and the late one on the Twenty-third. Rebbi Yose said, the early one on the Seventeenth, the average one on the Twenty-third, and the late one on the Thirtieth day, since we find that particular people only start to fast on the New Moon of Kislev.” Rebbi Abbamari, the brother of Rebbi Yose, said: everybody agrees that the Seventeenth is the time for the pleiads to disappear, since on it the Deluge came over the world. What is the reason? On this day all sources of the deep abyss were opened. Rebbi Abba bar Zamina, Rebbi Eleazar in the name of Rebbi Hoshaia: Practice follows him who says, “on the Third of Marḥeshwan one prays for rain”. And why did he not say, following Rebbi Meïr? There are Tannaim who switch.

It was stated: “On a Ninth of Av which falls on a Friday he eats even an egg and drinks even a cup full, in order not to enter the Sabbath being deprived, the words of Rebbi Jehudah. Rebbi Yose says, he fasts and finishes.” Rebbi Ze`ira in the name of Rav Jehudah, Rebbi Immi bar Ezechiel in the name of Rav: Practice follows him who says, he fasts and finishes. Why does he not say, practice follows Rebbi Yose? There are Tannaim who switch the names of the sages. Rebbi Ze`ira in the name of Rav Ḥuna: Even an individual who decided for himself to fast on a Friday fasts and finishes. As the following: Rebbi Bevai was sitting before Rebbi Yasa; he wanted to learn from him this matter. He said, let me go home a little bit. He said to him, it is afternoon. He answered, I am fasting. He said to him, I have lupines with me. He answered, and one finishes following Rebbi Yose.

We have stated: Jehudah ben Ṭabbai was Patriarch, and Simeon ben Shetaḥ President of the Court; there are Tannaim who switch. What happened in Alexandria supports him who said, Jehudah ben Tabbai was Patriarch. [The people of Jerusalem] wanted to appoint him Patriarch in Jerusalem. The people from Jerusalem did write: From the great Jerusalem to the small Alexandria: How long still will my betrothed live in your midst and I am sitting sorrowful about him? He took leave and started on a ship. He said, I remember the lady of the house who received us; what is she missing? One of his students told him, her eye is damaged. He told him, you have sinned twice; first that you suspected me, and second that you looked at her. Did I say that she was beautiful in looks? I only said that about her deeds. He was taking offense and he left.

Rav Ḥiyya bar Ashi in the name of Rav: One is permitted to knit a net on the holiday to catch fish on the holiday. Rav Jehudah instructed that sieves may be made on the holiday for the needs of the holiday. Rebbi Immi instructed that pompa may be made on the holiday for the needs of the holiday. The rabbis of Caesarea are saying, one fires pans and pots for the needs of the holiday. Samuel said, one pitches barrels but one does not pitch pitchers. One pitches barrels since the pitch is thin; one does not pitch pitchers since the pitch is glazed. Some do switch: one pitches pitchers but one does not pitch barrels. One pitches pitchers since this is for immediate use; one does not pitch barrels, since this is for storage.

They wanted to excommunicate Rebbi Eliezer. They said, who will go and inform him? Rebbi Aqiba said, I shall go and inform him. He went to him and said to him, my teacher, my teacher, your colleagues are excommunicating you. He took him outside, saying: Carob tree, carob tree, if practice has to follow their words, be uprooted. It was not uprooted. If practice has to follow my words, be uprooted. It was uprooted. If practice has to follow their words, turn back. It did not turn back. If practice has to follow my words, turn back. It turned back. All these extraordinary happenings and practice do not follow Rebbi Eliezer. Rebbi Ḥanina said, when it was given, it also was given to follow the majority opinion. [Did Rebbi Eliezer not know that practice has to follow the majority opinion?] He was offended only because they burned his food prepared in purity in his presence. There we have stated: “If it was cut into strips and sand was placed between any two strips, Rebbi Eliezer declares pure but the Sages declare impure. This is the Ḥakhinai oven.” Rebbi Jeremiah said, a big itching was happening on that day: Everything on which Rebbi Eliezer gazed was burned. Not only that, but a grain of wheat might have been half burned and half not burned, and the walls of the house of assembly were weakened. Rebbi Joshua said to them, if colleagues are fighting, what does this concern you? There came an unembodied voice and said, practice follows My son Eliezer. Rebbi Joshua said, it is not in Heaven. Rebbi Crispus, Rebbi Joḥanan in the name of Rebbi: If a person would say to me, that is how Rebbi Eliezer stated, I am stating following his words since the Tannaïm switch. Once he was walking in public and he saw a woman when sweeping her house throwing it out, it fell on his head. He said, it seems that today my colleagues are befriending me, for it is written: He lifts the downtrodden from the dung heap.

From where in the Torah that mourning is seven {days}? He organized seven days of mourning for his father. Can you infer anything from before the giving of the Torah? Rebbi Jacob bar Aḥa in the name of Rebbi Ze`ira understood it from the following: At the door of the Tent of Meeting you shall sit day and night for seven days, and keep the watch of the Eternal’ s sanctuary. Just as the Holy One, praise to Him, watched over His World for seven {days}, so you shall watch for your brothers for seven {days}. And from where that the Holy One, praise to Him, watched over His World for seven {days}? It was after seven days that the Deluge came over the world. May one mourn before the dying person dies? Only flesh and blood who do not know what will be in the future do not mourn until the dying person dies. But the Holy One, praise to Him, Who knows what will be in the future did first watch for His world. Some want to say, these are the seven days of mourning for Methusela the Just. Rebbi Hoshaia said, for the Eternal’s anointing oil is on you. Just as you were anointed with the anointing oil all of seven, so watch for your brothers all of seven. Rebbi Abbahu in the name of Rebbi Joḥanan: please let her not be like the dead. She shall be locked away. Just as the day of isolation for the dead are seven, so the days of quarantine are seven. One student reported this from Rebbi Joḥanan before Rebbi Simeon ben Laqish, who did not accept it. He said, here he uses it for isolation, but there he uses it for making absolute, as Rebbi Joḥanan said in the name of Rebbi Yannai, please let her not be like the dead: just as the days of the dead are not counted, so the days of being absolute are not counted. Rebbi Jeremiah and Rebbi Ḥiyya in the name of Rebbi Simeon ben Laqish; Rebbi Abbahu, Rebbi Yose ben Ḥanina in the name of Rebbi Simeon ben Laqish: the days of crying of the mourning for Moses ended. “The days”, seven. “Of crying”, two. “Mourning”, thirty. Some switch, “the days”, two, “of crying”, seven, “mourning”, thirty. Rebbi Yose, Rebbi Ḥiyya, and Rebbi Simeon ben Laqish in the name of Rebbi Judah the Patriarch: I shall turn your holiday into mourning. Since the days of Tabernacles are seven, also the days of mourning are seven. Rebbi Immi said to Rebbi Ḥiyya bar Abba: Maybe since the days of Tabernacles are eight, also the days of mourning are eight? He answered him, the eighth day is a separate holiday Or since Pentecost is one day, also mourning is one day? He answered him, from here about a deferred information. And it was stated such: Current information requires Seven and Thirty. Deferred information does not require Seven and Thirty.

Isaac, the son of the isatis grower, said that Rebbi Simeon ben Laqish asked, should we state sixteen women? Ḥalîṣah frees her co-wife! Rebbi Jacob the Southerner said before Rebbi Yose, why was this not stated? Because of Rebbi Aqiba, since Rebbi Aqiba said there is a bastard from a woman who got ḥalîṣah. One should have stated it for the rabbis! We came to state only things everybody agreed to. It turns out that Isaac, the son of the isatis grower, holds with Rebbi Immi. Rebbi Yasa said, Rebbi Joḥanan and Rebbi Simeon ben Laqish disagreed. Rebbi Joḥanan said, he is not guilty for the woman who got ḥalîṣah, but the brothers are guilty for the woman who got ḥalîṣah. Both he and the brothers are guilty for the co-wife. Rebbi Simeon ben Laqish said, neither he nor the brothers are guilty for the woman who got ḥalîṣah or for the co-wife. Rebbi Immi switches the attributions. Rebbi Ze‘ira said before Rebbi Yasa, does not Rebbi Immi switch the attributions? But Rebbi Joḥanan had several opinions. Did Rebbi Simeon ben Laqish have several opinions? The statement of Isaac, the son of the isatis grower, supports Rebbi Immi and the statements of the rabbis support Rebbi Yasa, as both Rebbi Jeremiah, Rebbi Abba, said in the name of Rebbi Ḥiyya bar Abba: Everybody agrees about the co-wife that one is guilty. Where do they disagree? About the woman who got ḥalîṣah. Rebbi Joḥanan said, he is not guilty for the woman who got ḥalîṣah, but the brothers are guilty for the woman who got ḥalîṣah.

HALAKHAH: Commandment prohibition: Incest prohibitions instituted by the Sopherim; it is a biblical commandment to listen to the words of the Sopherim. And Holiness prohibition: A widow for the High Priest, a divorcee or one who had ḥalîṣah for a simple priest. “These are the commandments,” all commandments are one. “ You should sanctify him, for he brings the bread of your God.” But some do switch: A widow for the High Priest, a divorcee or one who had ḥalîṣah for a simple priest, “you should sanctify him, for he brings the bread of your God.” “These are the commandments,” all commandments are one. And holiness prohibitions, incest prohibitions instituted by the Sopherim.

“He shall not marry an adult; Rebbi Eleazar and Rebbi Simeon enable the adult.” They agree that he shall not marry one injured by a piece of wood. What is the difference between the adult and the one injured by a piece of wood? The hymen of an adult dissolved in her body. The hymen of one injured by a piece of wood came outside. Some switch: He shall not marry one injured by a piece of wood; Rebbi Eleazar and Rebbi Simeon enable one injured by a piece of wood.” They agree that he shall not marry an adult. What is the difference between the adult and the one injured by a piece of wood? An adult is no longer young. The one injured by a piece of wood is still young.

It was stated: But he may walk on it until he reaches the entrance of his courtyard. Rebbi Aḥa and Rebbi Ze‘ira were walking on the highway. The sandal of Rebbi Aḥa was torn. When they came to the city gate, Rebbi Ze‘ira told him, that is the entrance of your courtyard. Rebbi Aḥa wound a fiber around. Rebbi Abbahu wound a bundle of Jew’s mallow. Rebbi Abbahu was of the opinion that a bundle of Jew’s mallow is ready to be used. Rebbi Jonah threw them away before the fried food store. That is little honor. The honor of Rebbi Eleazar obliged him to take it off. Rebbi Jeremiah asked before Rebbi Ze‘ira: May one switch? He said to him, it is permitted. Nevertheless, he told him: go and look for an Elder and rely on him. He went out and found Rebbi Abba bar Mamal, asked him, and he permitted. Rebbi Yose said, the Mishnah said that this is clothing, since we have stated: “Or with a left [foot sandal] on the right [foot], the ḥalîṣah is valid.” That means, in width. But in length it must cover most of the foot.

“ ‘From today if I should die, from now if I should die,’ that is a bill of divorce. ‘From today after my death’ is no bill of divorce.” Rebbi Yudan said, the rabbis and our teachers [discussed.] Our teachers objected to the rabbis: Why do you say, it is a bill of divorce? Because he said, “if”! But in the last statement, he said “if” and you say, it is no bill of divorce! But it must be because he said, “from today”. We also hold that “from today” is the main point. Rebbi objected to the rabbis. Why do you say, it is not a bill of divorce? Because he said, “from today”! But in the earlier statement, he said “from today” and you say, it is a bill of divorce! But it must be because he said, “if”. I also am holding that “if” is the main point. There, they switch attributions. Both Rebbi Yasa in the name of Rebbi Joḥanan and Rav say that the words of Rebbi [interpreted] there are the words of the rabbis [interpreted] here: Since he said “from today” it is as if he had said “on condition.” Rebbi Ze‘ira asked before Rebbi Yasa, “on condition that I die” or “on condition that it be after my death”? He said to him, “on condition that I die.” Rebbi Abba in the name of Rav: The words of Rebbi [interpreted] here are the words of the rabbis [interpreted] there: Since he said “from today” it is as if he had said “after death.”

“But the Sages say, small animals are taken possession of by drawing near.” What is the reason of the rabbis? “Draw near and take for yourselves small animals for your families.” As Rav Jehudah sent to ask: By what means is possession of large animals established? He answered, by handing over; and asked, is that not the Mishnah? There are Tannaïm who switch the attributions. Rav Jehudah asked Rebbi Eleazar: If a firstborn became “torn” within thirty days? He answered, he is as if dead and free from the five tetradrachmas of a son. Rav Jehudah sent and asked Rebbi Eleazar: A placenta which was delivered partially today and partially tomorrow? He answered, for pure blood she counts from the first day, for impure blood from the second day. Rebbi Mattaniah said, that is, if no child was produced with it. But if there was a child, both for pure and impure blood she counts only from the moment of birth of the child.

If somebody produced both a document and ḥazaqah. Rebbi says, it should be judged by the document. Rabban Simeon ben Gamliel says, it should be judged by ḥazaqah. Rebbi Ze`ira in the name of Rav Jeremiah: A case came before Rebbi Jehudah following Rabban Simeon ben Gamliel. Rebbi Jeremiah asked before Rebbi Ze`ira: How? Did Rebbi switch his opinion? There he said, it should be judged by the document. But here he said it should be judged by ḥazaqah. Would we say, before he changed his opinion? Even if you say, after he changed his opinion. Rebbi only wanted to determine the truth of the matter. “If somebody occupied real estate on the basis of a document of sale and it was found invalid, this is not ḥazaqah.” Rebbi Jeremiah said, in dispute. Rebbi Samuel said, Rebbi Ze`ira, Rebbi Jacob bar Aḥa in the name of Rebbi Abinna: it is everybody’s opinion. Rebbi Yose said, there if one produced both a document and ḥazaqah. Here if he came with a document. Rebbi Yudan said, there if he presented two groups of witnesses; here one who contradicts his own proofs.
