sheretz

The blood of those who walk on two [legs] is like the blood of beasts in that it renders seeds susceptible [to impurity]. And it is like the blood of a sheretz, in that one is not liable for eating it.

With regard to a thigh-bone of a corpse or a thigh-bone of a consecrated animal, he who touches it, whether it be stopped up or pierced, becomes unclean. With regard to a thighbone of a nevelah or of a [dead] sheretz, if it was stopped up, he who touches it remains clean, but if it was at all pierced it conveys uncleanness by contact. From where do we know [the same rules apply] for carrying? Scripture says, “He that touches and he that carries” (Leviticus 11:39-40), anything that [can become unclean] by contact [can become unclean] by carrying. And anything that cannot [become unclean] by contact, cannot become [unclean] by carrying.

The egg of a sheretz in which there has formed an embryo is clean. If it was pierced, however small the hole was, it is unclean. A mouse which is half flesh and half earth, if a man touched the flesh he becomes unclean, but if he touched the earth he remains clean. Rabbi Judah says: even if he touched the earth that is over against the flesh he becomes unclean.

All kinds of piggul can combine with one another and all kinds of notar can combine with one another. All kinds of carrion can combine with one another. All kinds of sheratzim can combine with one another. The blood of a sheretz and its flesh can combine with one another. A general rule was stated by Rabbi Joshua: all things that are alike both in respect of [duration of] uncleanness and in respect of their minimum measure can combine with one another. Things that are alike in respect [of duration] of uncleanness but not in respect of minimum measure, in respect of minimum measure but not in respect [of duration] of uncleanness, or [if they are alike] neither in respect [of duration] of uncleanness nor in respect of measure, cannot combine with one another.

Piggul and remnant do not combine with one another because they are of two different names. Sheretz and carrion, as well as carrion and the flesh of a corpse do not combine with one another to effect impurity, not even in respect of the more lenient of the two [grades] of defilement. Food contaminated through contact with a primary defilement can combine with that contaminated by a secondary defilement to affect uncleanness according to the lower degree of defilement of the two.

The fathers of impurity are a: sheretz, semen, [an Israelite] who has contracted corpse impurity, a metzora during the days of his counting, and the waters of purification whose quantity is less than the minimum needed for sprinkling. Behold, these convey impurity to people and vessels by contact and to earthenware by presence within their airspace, But they do not convey impurity by being carried.

An oven which they partitioned with boards or hangings, and in it was found a sheretz in one compartment, the entire oven is unclean. A hive which was broken and its gap was stopped up with straw and was suspended within the air-space of an oven while a sheretz was within it, the oven becomes unclean. If a sheretz was within the oven, any food within the hive becomes unclean. But Rabbi Eliezer says that it is clean. Rabbi Eliezer said: if it affords protection in the case of a corpse which is more consequential, should it not afford protection in the case of an earthenware vessel which is less consequential? They said to him: if it affords protection in the case of corpse impurity, this is because tents are divided, should it also afford protection in the case of an earthenware vessel which is not divided?

If the hive was complete, and so too in the case of a basket or a skin-bottle, and a sheretz was within it the oven remains clean. If the sheretz was in the oven, any food in the hive remain clean. If a hole was made in it: A vessel that is used for food must have a hole large enough for olives to fall through, If it is used for liquids the hole must be large enough for liquids to pass into it, And if it is used for either it is subjected to the greater restriction: the hole need only be large enough for liquids to pass into it.

Netting placed over the mouth of an oven and slightly sinking into it, and having no frame: If a sheretz was in it, the oven becomes unclean; If the sheretz was in the oven, the food in the netting becomes unclean, since only vessels afford protection against an impurity in an earthen vessel. A jar full of pure liquids placed beneath the bottom of an oven, and a sheretz in the oven – the jar and the liquids remain clean. If it was inverted, with its mouth projecting into the air-space of the oven, and a sheretz was in the oven, the liquid that clings to the sides of the jar remains clean.

A pot which was placed in an oven if a sheretz was in the oven, the pot remains clean since an earthen vessel does not impart impurity to vessels. If it contained dripping liquid, the latter contracts impurity and the pot also becomes unclean. It is as if this one says, "That which made you unclean did not make me unclean, but you have made me unclean."

If a rooster that swallowed a sheretz fell within the air-space of an oven, the oven remains clean; If the rooster died, the oven becomes unclean. If a sheretz was found in an oven, any bread in it contracts second degree impurity since the oven is of the first degree.

A leavening pot with a tightly fitting lid which was put in an oven, and there was some leaven and a sheretz within the pot, but there was a partition (of inedible bread) between them, the oven is unclean but the leaven is clean. But if it was an olive's bulk of corpse, both the oven and the house are unclean, and the leaven remains clean. If in the partition there was an opening of one handbreadth, all become unclean.

A sheretz which was found in the eye-hole of an oven or of a double stove or of a single stove: If it was outside the inner edge, it is clean. If it [the oven] was in the open air, even if it was an olive's bulk of corpse it is clean. If there was [in the eye-hole] an opening of one handbreadth, it is all unclean.

If a sheretz was found in the [place in a stove] where wood is put: Rabbi Judah says: if it was within the outer edge, [the stove] becomes unclean. But the sages say: if it was outside the inner edge [the stove] remains clean. Rabbi Yose says: if it was found beneath the spot where the pot is placed and inwards, the stove becomes unclean, but if beneath the spot where the pot is set and outwards, it remains clean. If it was found on the place where the bath-keeper sits, or where the dyer sits, or where the olive-boilers sit, the stove remains clean. It only becomes unclean only [when the sheretz] is found in the enclosed part and inwards.

If a sheretz was found beneath the bottom of an oven, the oven remains clean, for I can assume that it fell there while it was still alive and that it died only now. If a needle or a ring was found beneath the bottom of an oven, the oven remains clean, for I can assume that they were there before the oven arrived. If it was found in the wood ashes, the oven is unclean since one has no ground on which to base an assumption of cleanness.

A stopper of a jar that is loose but does not fall out: Rabbi Judah says: it protects. But the sages say: it does not protect. If its finger-hold was sunk within the jar and a sheretz was in it, the jar becomes unclean. If the sheretz was in the jar, any food in it, become unclean.

If [earthenware] pans were placed one within the other and their rims were on the same level, and there was a sheretz in the upper one or in the lower one, that pan alone becomes unclean but all the others remain clean. If [they were perforated] to the extent of admitting a liquid, and the sheretz was in the uppermost one, all become unclean. If in the lowest one, that one is unclean while the others remain clean. If the sheretz was in the uppermost one and the lowest projected above it, both are unclean. If the sheretz was in the uppermost one and the lowest projected above it, any one that contained dripping liquid becomes unclean.

If a mattress was wrapped around a bed and a corpse touched them, they are subject to a seven-day uncleanness; If they are taken apart they are still subject to a seven-day uncleanness. If a sheretz touched them they are subject to an evening uncleanness; If they are taken apart they are still subject to evening uncleanness. A bed from which the two longer sides were removed and two new ones were prepared for it but the original sockets were not changed: If the new sides were broken the bed retains its uncleanness, But if the old ones were broken it becomes clean, since all depends on the old ones.

Whole limbs [of the body] have no [restriction as to] size: even less than an olive-sized portion of a corpse or less than an olive-sized portion of nevelah (carrion), or less than a lentil-sized portion of a sheretz can defile, [each in the manner of] their respective defilements.

[An object] one handbreadth square and one handbreadth high conveys uncleanness and blocks uncleanness. How does it [block uncleanness]? In the case of a covered drain beneath a house, if it has a space a handbreadth wide and its outlet was a handbreadth wide, and there is uncleanness inside it, the house remains clean; And when there is uncleanness in the house, that which is within [the drain] remains clean, for the manner of the uncleanness is to go out and not to go in. If it had a space one handbreadth wide but its outlet was not one handbreadth wide, when there is uncleanness in it, the house becomes unclean; But when there is uncleanness in the house, that which is within it remains clean, for the manner of the uncleanness is to go out and not to go in. If it did not have a space one handbreadth wide and its outlet was not one handbreadth wide, when there is uncleanness within it, the house becomes unclean; And when there is uncleanness in the house, it [also] becomes unclean. It makes no difference if the cavity was carved out by water or by a sheretz or if it had been eaten out by salt. And similarly [if it is in] a row of stones or a pile of beams. Rabbi Judah says: any "tent" not made by a person is not considered a tent’. But he agrees that crevices and crags [can be considered as ‘tents’].

The following [objects serve to] reduce [the area of a square] handbreadth: [A portion] of less than an olive-size of flesh [of a corpse] reduces [the opening for uncleanness that is] caused by a quarter of a kav of bones [from a corpse]; [A portion] of less than a barley-corn size of bone reduces [the opening for uncleanness that is] caused by an olive-sized portion of flesh; Less than an olive-sized portion of a corpse, Less than an olive-sized portion of carrion, Less than a lentil-sized portion of sheretz; Less than an egg-sized portion of food; Produce growing next to the window, A cobweb having substance; The carcass of a clean bird that he did not intend to eat, And the carcass of an unclean bird that had been intended [for food] that had not been rendered susceptible [to uncleanness], or which had been rendered susceptible [to uncleanness] but had not been intended [for food].

He now comes to set free the living bird. He does not turn his face towards the sea or towards the city or towards the wilderness, for it is said, "But he shall let the living bird go out of the city into the open field" (Leviticus 14:53). He now comes to shave off the hair of the metzora. He passes a razor over the whole of his skin, and he [the metzora] washes his clothes and immerses himself. He is then clean so far as to not convey uncleanness by entrance, but he still conveys uncleanness as does a sheretz. He may enter within the walls [of Jerusalem], but must keep away from his house for seven days, and he is forbidden to have intercourse.

On the seventh day he shaves off his hair a second time in the manner of the first shaving, he washes his garments and immerses himself. He is clean in so far as not to convey uncleanness as a sheretz, but he was still like a tevul yom. He may eat second tithe. After sunset he may eat terumah. After he had brought his offering of atonement, he may also eat sacred things. Thus there are three grades in the purification of a metzora and three grades in the purification of a woman after child birth.

A jar of hatat waters that touched a [dead] sheretz, remains clean. If the jar was put on it: Rabbi Eliezer rules that it remains clean, And the sages rule that it becomes unclean. If the jar touched foods or liquids or the Holy Scriptures, it remains clean. If it was put on them: Rabbi Yose rules that it remains clean; And the sages say that it becomes unclean.

Pieces of dough which are stuck to each other or loaves stuck to each other, if one of them was defiled from a sheretz, they all become unclean in the first degree; If they were then separated they are still regarded as having first degree uncleanness. If one of them was defiled by a liquid they all have second degree uncleanness; If they were then separated they are still regarded as have second degree uncleanness. If one of them was defiled from the hands, they all become have third degree uncleanness; If they were then separated they are still regarded as having third degree of uncleanness.

Holy loaves in whose hollows there was holy water, if one contracted uncleanness from a sheretz, they all become unclean. In the case of loaves of terumah, uncleanness is conveyed to two loaves and one is invalidated. If there was dripping liquid between them, even in the case of terumah all become unclean.

If an egg's bulk of food was left in the sun and it was lessened, and so also in the case of an olive's bulk of corpse, an olive's bulk of carrion, a lentil's bulk of a sheretz, an olive's bulk of piggul, an olive's bulk of notar, or an olive's bulk of forbidden fat they become clean; Nor is one liable on account of these for transgressing the law of piggul, notar or forbidden fat. If they were then left out in the rain and they swelled, they become unclean and guilt is incurred on account of them for transgressing the law of piggul, notar or forbidden fat.

A dead sheretz that was held in the mouth of a weasel that was passing over loaves of terumah and it is doubtful whether the sheretz did or did not touch them, in such condition of doubt [the loaves] are clean.

A dead sheretz that was held in the mouth of a weasel that was passing over loaves of terumah and it is doubtful whether the sheretz did or did not touch them, in such condition of doubt [the loaves] are clean.

A weasel that had in its mouth a [dead] sheretz or a dog that had carrion in its mouth and they passed between clean [persons] or if clean persons passed between them, their condition of doubt is deemed clean, since the uncleanness , had no resting place. If they were picking at them while these lay on the ground, and a person stated, "I went to that place but I do not know whether I did or did not touch it," his condition of doubt is deemed unclean, since the uncleanness had a resting place.

An olive's bulk of corpse was held in a raven's mouth and it is doubtful whether it overshadowed a person or vessels in a private domain: The person's condition of doubt is deemed to be unclean But the vessels’ condition of doubt is deemed clean. One who drew water in ten buckets and a dead sheretz was found in one of them, it alone is deemed unclean but all the others remain clean. If one poured out from one vessel into another and a dead sheretz was found in the lower vessel, the upper one remains clean.

An olive's bulk of corpse was held in a raven's mouth and it is doubtful whether it overshadowed a person or vessels in a private domain: The person's condition of doubt is deemed to be unclean But the vessels’ condition of doubt is deemed clean. One who drew water in ten buckets and a dead sheretz was found in one of them, it alone is deemed unclean but all the others remain clean. If one poured out from one vessel into another and a dead sheretz was found in the lower vessel, the upper one remains clean.

These are the cases of doubtful uncleanness that the sages declared to be clean: A doubt concerning drawn water for a mikveh, A doubt concerning an object of uncleanness that floated upon the water. A doubt concerning liquids as to whether they have contracted uncleanness it is deemed unclean, but if it was whether uncleanness has been conveyed it is deemed clean. A doubt concerning the hands as to whether they have contracted uncleanness, have conveyed uncleanness or have attained cleanness, they are deemed clean. A doubt that arose in a public domain; A doubt concerning an ordinance of the scribes; A doubt concerning non-sacred food; A doubt concerning a sheretz; A doubt concerning negaim; A doubt concerning a nazirite vow; A doubt concerning a first-born; A doubt concerning sacrifices.

"A condition of doubt concerning non-sacred food"--this refers to the cleanness practiced by Pharisees. "A condition of doubt concerning a sheretz" –according [to their condition at] the time they are found. "A condition of doubt concerning negaim" it is deemed clean in the beginning before it had been determined to be unclean, but after it had been determined to be unclean, a condition of doubt is deemed unclean. "A condition of doubt concerning a nazirite vow" [in such a condition of doubt he] is permitted [all that is forbidden to a nazirite]. "A condition of doubt concerning first-borns" whether they are human firstborn or firstborn of cattle, whether the firstborn of an unclean beast or a clean one, for the one who wishes to extract from his fellow bears the burden of proof.

A [dead] sheretz and a [dead] frog in a public domain, And so also [if there was there] an olive's bulk of a corpse and an olive's bulk of carrion, A bone of a corpse and a bone of carrion; A clod of clean earth and a clod from a doubtful grave area A clod of clean earth and a clod from the land of the Gentiles, Or if there were two paths, the one unclean and the other clean, and a man walked through one of them but it is not known which, Or if overshadowed one of them but it is not known which, or he shifted one of them but it is not known which: Rabbi Akiva rules that he is unclean, But the sages rule that he is clean.

If there was a sheretz and a frog in a public domain and a man touched one of them and then prepared clean foods which were subsequently consumed; and then he immersed, and then he touched the other and then prepared clean foods, the latter are deemed clean. If the first foods were still in existence both must be held in suspense. If he did not immerse in the meanwhile, the first are held in suspense and the second must be burnt .

If a [dead] sheretz was found in the milling stones, only the place that it has touched becomes unclean. But if moisture was running, all become unclean. If it was found on the leaves, the olive-press men shall be asked whether they can say, "we did not touch it." If it touched the mass [of olives], even by as little as the bulk of a barley grain, [the mass becomes] unclean.

If one is emptying out the cistern [into jars] and a [dead] sheretz was found in the first jar, all the other jars are deemed unclean; but if it was found in the last, only that one is unclean but all the others remain clean. When does this apply? When the wine was drawn directly with each jar, but if it was drawn with a ladle and a [dead] creeping thing was found in one of the jars, it alone is unclean. When does this apply? Only when the man examined [the jars] but did not cover them up or covered them up but did not examine them; But if he both examined them and covered them up and a [dead] creeping thing was found: If in one jar, all the contents of the cistern are deemed unclean. If it was found in the cistern, all its contents are deemed unclean And if it was found in the ladle all the contents of the cistern are deemed unclean.

Mikvaot can be joined together [if their connection is as big] as the tube of a water-skin in thickness and in space, in which two fingers can be fully turned round. If there is a doubt [whether it is as big] as the tube of a water skin or not, it is invalid, because [this is a mitzvah] from the Torah. The same applies also to the olive's bulk of a corpse and the olive's bulk of carrion and the lentil's bulk of a sheretz. Anything which remains in [the space measuring] the tube of a water-skin lessens [its measure]. Rabban Shimon ben Gamaliel says: if it is any water creature whatsoever, [the mikvaot] remain clean.

The blood of a menstruant and the flesh of a corpse convey uncleanness when wet and when dry. But the discharge [of a zav], and the phlegm [of a zav] and the spittle [of a zav], a dead sheretz, a nevelah and semen convey uncleanness when wet but not when dry. If they can be soaked and then revert to their original condition they convey uncleanness when wet and when dry. And how long must they be soaked? In lukewarm water for a period of twenty four hours. Rabbi Yose says: If the flesh of a corpse is dry, and it cannot be soaked and brought back to its original condition, it is clean.

If a dead sheretz was found in an alley it causes uncleanness retrospectively to such time as one can say, "I examined this alley and there was no sheretz in it," or to such time as it was last swept. So also a bloodstain found on a garment causes uncleanness retrospectively to such time as one can say, "I examined this shirt and there was no stain on it" or to such time as it was last washed. And it conveys uncleanness whether it is wet or dry. Rabbi Shimon says: if it is dry it causes uncleanness retrospectively, but if it is wet it causes uncleanness only to a time when it could still have been wet.

Derivatives of water are: the liquids that come from the eye, from the ear, from the nose and from the mouth, and urine, whether of adults or of children, whether [its flow is] conscious or unconscious. Derivatives of blood are: blood from the slaughtering of cattle and wild animals and birds that are clean, and blood from bloodletting for drinking. Whey is like milk, And the sap of olives is deemed like oil, since it is never free from oil, the words of Rabbi Shimon. Rabbi Meir says: even though it contains no oil. The blood of a sheretz is like its flesh, it causes uncleanness but does not cause susceptibility to uncleanness, and there is nothing else like it.

He who touches a dead sheretz, or semen, or he that has suffered corpse uncleanness, or a metzora during his days of counting, or hatat waters of insufficient quantity with which to perform the sprinkling, or carrion, or an object ridden upon [by a zav], defiles at one [remove] and disqualifies [terumah] at one [more remove]. This is the general principle: anyone who touches anything that according to the Torah is a "father of uncleanness" defiles at one [remove] and disqualifies [terumah] at one [more remove], except [for the corpse] of a human. If he had become separated, he defiles at one [remove] and renders [terumah] unfit at one [more remove].

He who has had a seminal emission is like one who has touched a dead sheretz. And one who has had sex with a menstruant is like one who has suffered corpse uncleanness. But one who has had sex with a menstruant is more stringent in that he conveys minor grades of uncleanness to what he lies or sits upon, so as to make foods and liquids unclean.
