Mishnah Oholot 3:1

All objects that defile by overshadowing which were divided and then brought into a house: Rabbi Dosa ben Harkinas declares clean. But the sages declare [it] unclean. What is the case? One who touches two pieces of nevelah, each the size of half an olive, or carries them, Or, in the case of a corpse, if he touches a piece the size of half an olive and overshadows [another piece] the size of half an olive, Or if he touches [a piece] the size of half an olive and [another piece] the size of half an olive overshadows him, Or if he overshadows two [pieces, each] the size of half an olive, Or if he overshadows [a piece] the size of half an olive and [another piece] the size of half an olive overshadows him: Rabbi Dosa ben Harkinas declares him clean, And the sages declare him unclean. But if he touches [a piece] the size of half an olive and another object overshadows him and [another piece] the size of half an olive, Or if he overshadows [a piece] the size of half an olive and another object overshadows him and [another piece] the size of half an olive, he is clean. Rabbi Meir says: Even here Rabbi Dosa ben Harkinas declares him clean and the sages declare him unclean. Every [case] is unclean except [a case of] contact [combined] with carriage or of carriage [combined] with overshadowing. This is the general principle: every object [whose defilement] proceeds from one cause is unclean, from two causes is clean.

Mishnah Oholot 3:2

If a ladleful of corpse-mold was scattered about in a house, the house is unclean But Rabbi Shimon declares it clean. If a quarter [of a log] of blood was absorbed in [the ground] of a house, the house is clean. If it was absorbed by a garment: if the garment is washed and a quarter [of a log] of blood emerges from it, it is unclean, if not, it is clean, since anything absorbed that cannot emerge is clean.

Mishnah Oholot 3:3

[Blood] which was poured out in the air: If the place [where it fell] was an incline and [a person or vessel] overshadowed part of it, he [remains] clean. If it was a cavity, or if the blood congealed, he [becomes] unclean. If it was poured out on a threshold: If it inclined either inwards or outwards and the house overshadowed it [that which is in the house] is clean. If there was a cavity, or if it congealed, [that which is in the house becomes] unclean. Every part of a corpse is unclean except the teeth, hair and nails; But when they are joined [to the corpse], they are all unclean.

Mishnah Oholot 3:3

[Blood] which was poured out in the air: If the place [where it fell] was an incline and [a person or vessel] overshadowed part of it, he [remains] clean. If it was a cavity, or if the blood congealed, he [becomes] unclean. If it was poured out on a threshold: If it inclined either inwards or outwards and the house overshadowed it [that which is in the house] is clean. If there was a cavity, or if it congealed, [that which is in the house becomes] unclean. Every part of a corpse is unclean except the teeth, hair and nails; But when they are joined [to the corpse], they are all unclean.

Mishnah Oholot 3:4

How so? If the corpse was outside and its hair inside, the house is unclean.

[With regard to] two bones which had upon them two pieces of flesh, [each] the size of half an olive, if one brought part of them within so that the house was overshadowing them, [the house] is unclean. But if [the pieces of flesh] were set into [the bone] by a person, the house is clean since connections created by human agency are not [regarded as] connections.

Mishnah Oholot 3:5

What is ‘mixed blood? The blood of a corpse of which an eighth [of a log] came out during his lifetime and an eighth after death, the words of Rabbi Akiva. Rabbi Ishmael says: a quarter [of a log] during his lifetime and a quarter after death. [If] a quarter [of a log] is taken from both of these: Rabbi Elazar bar Judah says: both of these are as water. What then is ‘mixed blood’? It is that of a crucified person whose blood is streaming forth and under whom is found a quarter [of a log] of blood it is unclean. However a corpse whose blood drips forth and under whom is found a quarter [of a log] of blood, [the blood] is clean. Rabbi Judah says: not so, but that which streams forth is clean and that which drips forth is unclean.

Mishnah Oholot 3:6

For an olive-sized portion of a corpse, an opening [in the room in which it is found] of one handbreadth [square], and for a [whole] corpse, an opening of four handbreadths [square, is enough] to prevent the uncleanness from [spreading to the other] openings; But for allowing the uncleanness to go out, an opening of one handbreadth [square is enough]. [A portion] greater than the size of an olive is as a [whole] corpse. Rabbi Yose says: [only] the spine and the skull are as a [whole] corpse.

Mishnah Oholot 3:6

For an olive-sized portion of a corpse, an opening [in the room in which it is found] of one handbreadth [square], and for a [whole] corpse, an opening of four handbreadths [square, is enough] to prevent the uncleanness from [spreading to the other] openings; But for allowing the uncleanness to go out, an opening of one handbreadth [square is enough]. [A portion] greater than the size of an olive is as a [whole] corpse. Rabbi Yose says: [only] the spine and the skull are as a [whole] corpse.

Mishnah Oholot 5:1

[With regard to] an oven which stood in a house, with its outlet curved to the outside [of the house], and those burying a corpse overshadowed it: Bet Shammai says: all becomes unclean. Bet Hillel says: the oven becomes unclean, but the house remains clean. Rabbi Akiva says: even the oven remains clean.

Mishnah Oholot 6:2

If corpse-bearers were passing along a portico and one of them shut a door and locked it with a key, If the door can remain in its position on its own,[the contents of the house] remain clean, But if not, they become unclean. Similarly [in the case of] a barrel of dried figs or a basket of straw placed in a window, If the dried figs or the straw can remain in their position on their own, [the contents of the room] remain clean, But if not they become unclean. [In the case of] a house partitioned off by wine-jars, which had been plastered with clay, If the clay can remain in its position on its own, [the space partitioned off] remains clean, But if not, it becomes unclean.

Mishnah Oholot 7:3

If a corpse is in a house in which there are many doors, they all become unclean. If one of them was opened, that one becomes unclean but all the rest remain clean. If he intended to carry out the corpse through one of them or through a window of four hand breadths square, he protects all the other doors. Bet Shammai says: the intention must have been formed before the person died. Bet Hillel say: even after he died. If [a door] was blocked up and it was decided to open it: Bet Shammai says: [it is effective] as soon he opens a [a space] four handbreadths square. Bet Hillel says: as soon as [the process] has begun. They agree, however, that when making an opening for the first time, four handbreadths must be opened up.

Mishnah Oholot 8:6

Two [earthenware] jars in which there are two pieces of corpse the size of half an olive, sealed with tightly fitting lids, lying in a house, they remain clean, but the house becomes unclean. If one of them was opened, that [jar] and the house become unclean, but the other remains clean. And similarly with two rooms that open into a house.

Mishnah Oholot 9:1

A beehive [lying] in the doorway with its mouth [pointing] outside: If an olive-sized [portion] of a corpse were placed below the [part of the hive] which is outside [the house], Everything directly below or above that olive-sized [portion] becomes unclean; But everything that is not directly [below or above] that olive-sized [portion], or that which is within [the hive] or within the house, remains clean. [If the uncleanness is] within the house, nothing becomes unclean except that which is within the house. [If the uncleanness is] within [the hive] everything becomes unclean.

Mishnah Oholot 9:3

When do these rules apply? When the hive is a vessel and it is loosely placed in the door. If it is defective, although [it may be] stopped up with straw or it is stuck to the side of the door What is "stuck? Anything which has no opening of one handbreadth : Then, if an olive-sized [portion] of a corpse is placed below it, [everything] directly [below the portion] to the depths becomes unclean; [If placed] above [the hive everything] directly above to the sky becomes unclean. [If the uncleanness is] in the house, nothing becomes unclean except the house. [If the uncleanness is] within [the hive] nothing becomes unclean except that which is within [the hive].

Mishnah Oholot 9:5

When do these rules apply? When the mouth [of the hive is pointing] outwards If the mouth is [pointing] inwards [towards the house]: If an olive-sized portion of the corpse is placed below or above [that part of the hive which is] outside, everything directly below or above that olive-sized portion becomes unclean, and everything not directly [below or above it] and whatever is within [the hive] and the house, remains clean. [If the uncleanness is] within the hive or the house, everything becomes unclean.

[If the uncleanness is] in the house or in the hive, whatever is in the house or hive becomes unclean.

Mishnah Oholot 9:11

If it was lying on its side in the open air: If an olive-sized [portion] of a corpse was placed below it or above it, everything directly below or above the olive-sized [portion] becomes unclean; but everything that is not directly below or above, and what is within [the hive] remains clean. [If the uncleanness is] within [the hive] everything becomes unclean.

Mishnah Oholot 9:12

[In the case where the hive is in the open air] and is one handbreadth high off the ground, if there is uncleanness below it or above it, everything becomes unclean except the inside. [If the uncleanness is] within, everything becomes unclean. When do these rules apply? When [the hive is] a vessel. If it is defective, although [it may be] stopped up with straw or according to the sages, it contains forty seahs Then if an olive-sized [portion] of a corpse is placed below it, [everything] directly [below] to the depths becomes unclean; [If placed] above, [everything] directly above to the sky becomes unclean. [If the uncleanness is] is within [the hive] nothing is unclean except that which is within. [If] it was one handbreadth high off the ground, if there was uncleanness below it, what is below becomes unclean; [If the uncleanness] was within it, what is within becomes unclean; Above it, [everything] directly [above] to the sky becomes unclean.

Mishnah Oholot 9:15

A coffin which is broad below and narrow above, and has a corpse within it: A person touching it below remains clean; But above becomes unclean. If it is broad above and narrow below, a person touching it anywhere becomes unclean. If it was the same [above and below], a person touching it anywhere becomes unclean, the words of Rabbi Eliezer. But Rabbi Joshua says: a handbreadth and more below is clean, but from that handbreadth upwards is unclean. If it was made like a clothes-chest, a person touching it anywhere becomes unclean. If it was made like a case, a person touching it anywhere remains clean, except at the place where it opens.

Mishnah Oholot 9:16

A jar resting on its bottom in the open air: If an olive-sized [portion] of a corpse is placed beneath it or within it directly [above] its bottom, the uncleanness cleaves upwards and downwards, and the jar becomes unclean. [If the uncleanness is] outside below a [protruding] side, the uncleanness cleaves upwards and downwards, but the jar remains clean. [If the uncleanness is] within [the jar] and underneath the protruding sides, If there is within the [cavity of] the side a space of a cubic handbreadth everything [within the cavity] becomes unclean, but what lies directly [below] the mouth remains clean. If there is not [a space of a cubic handbreadth] the uncleanness cleaves upwards and downwards. When do these rules apply? When the jar is clean. If it was unclean, or if it was one handbreadth high off the ground, or covered, or inverted [so as to stand] on its mouth, if there is uncleanness beneath it, within it or above it, everything becomes unclean.

Mishnah Oholot 11:7

A dog which had eaten the flesh of a corpse and then died and was lying over the threshold: Rabbi Meir says: if its neck has a thickness of one handbreadth it can bring the uncleanness, but if not, it does not bring the uncleanness. Rabbi Yose says: we [examine to] see where the uncleanness is. If it is beneath the lintel and inwards, the house becomes unclean; if from the lintel and outwards, the house remains clean. Rabbi Eliezer says: if its mouth [points] inwards, the house remains clean; if its mouth [points] outwards, the house becomes unclean, since the uncleanness goes out through its hind. Rabbi Judah ben Batera says: in either case the house becomes unclean. How long can [the uncleanness] remain in its entrails? Three whole days. [If in the entrails] of fishes or birds, as long as [it takes for the uncleanness] to fall in the fire and be consumed, the words of Rabbi Shimon. Rabbi Judah ben Batera says: in the case of fishes or birds, twenty-four hours.

Mishnah Oholot 12:4

[With regard to] the shoe of a cradle, for which a hole had been made [in the ceiling to bring it] into the house [below], If [the hole] is one handbreadth square, everything becomes unclean; But if it was not [one handbreadth square] its [uncleanness] is reckoned as one reckons with [cases of contact with] a corpse.

Mishnah Oholot 12:8

If an olive-sized portion of a corpse is stuck to the threshold: Rabbi Eliezer declares the house unclean. Rabbi Joshua declares it clean. If it was placed beneath the threshold, the [case] is judged by the half [in which the uncleanness is found]. If it is stuck to the lintel, the house becomes unclean. Rabbi Yose declares it clean. If it was in the house, a person touching the lintel becomes unclean. [As for] a person touching the threshold: Rabbi Eliezer declares him unclean. Rabbi Joshua says: [if he touches it at a point] below a handbreadth [from the surface] he remains clean; above that handbreadth he becomes unclean.

Mishnah Oholot 13:5

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].

The following do not reduce [the area of the window]: Bone does not reduce [the area] for [other] bones; Nor [corpse] flesh for [other] flesh; Nor an olive-sized [portion] of a corpse; Nor an olive-sized portion of carrion; Nor a lentil-sized portion of reptile; Nor an egg-sized portion of food; Nor produce growing in the windows; Nor a cobweb having no substance; Nor the carcass of a clean bird which had been intended [for food]; Nor the carcass of an unclean bird which had been intended [for food] and had been rendered susceptible to uncleanness; Nor warp and woof threads that have negaim; Nor a brick from a bet haperas, the words of Rabbi Meir. But the sages say: the brick can reduce, because the dust [of the bet haperas] is clean. This is the general rule: what is clean reduces [the area], and what is unclean does not reduce it.

Mishnah Oholot 15:10

One who touches a corpse and touches vessels, one who overshadows a corpse and touches vessels, they [the vessels] are unclean. One who overshadows a corpse and overshadows vessels, one who touches a corpse and overshadows vessels, they [the vessels] are clean. If his hands are a handbreadth wide, they are unclean. Two houses, and in each there is a half an olive's worth of corpse and he puts one hand into each house: If his hands are a handbreadth wide, he brings uncleanness; But if not, he does not bring uncleanness.

Mishnah Oholot 16:1

All movable things convey uncleanness when they are of the thickness of an ox-goad. Rabbi Tarfon said: May I [see the] demise of my sons if this is [not] a demised halakhah which someone heard and misunderstood. For a farmer was passing by and over his shoulder was an ox-goad, and one end overshadowed a grave. He was declared unclean on account of vessels that were overshadowing a corpse. Rabbi Akiva said: I can fix [the halakhah] so that the words of the sages can exist [as they are]: All movable things convey uncleanness to come upon a person carrying them, when they are of the thickness of an ox-goad; Upon themselves when they are of whatever thickness; And upon other men or vessels [which they overshadow] when they are one handbreadth wide.

Mishnah Oholot 16:2

How so? A spindle stuck into the wall, with [a portion of corpse] of half an olive-size above it and [a portion of corpse] of half an olive-size below it. Even though one [portion] is not directly [above] the other, [the spindle] becomes unclean. Hence it is found that [a movable object] conveys uncleanness to come upon itself whatever its thickness. A pot seller passes by a grave with a yoke over his shoulder, one end of which overshadows a grave, vessels on the other side remain clean. If the yoke is one handbreadth wide, they become unclean. Mounds which are near to a city or to a road, whether they are new or old, are unclean. [As for those that are] far away, new ones are clean but old ones are unclean. What counts as near? Fifty cubits. And old? Sixty years old, the words of Rabbi Meir. R. Judah says: Near means there is none nearer than it, and old means that no one remembers [when it was made].

Mishnah Oholot 16:3

If one finds a corpse unexpectedly lying in its natural position, he may remove it along with the [blood-] saturated earth around it. If he finds two, he may remove them along with the [blood-] saturated earth around it. If he finds three, if there is a space of from four to eight cubits between the first and the last, that is, the space of a bier and its bearers, then it must be accounted a graveyard. He must search [the ground] for twenty cubits from that point. If he found [another corpse] at the end of those twenty cubits, he must search for a further twenty cubits from that place, since there are already grounds for belief [that this is a graveyard], in spite of the fact that if he had found this [lone grave] in the first case, he could have removed it with the [blood-] saturated earth around it.

Mishnah Negaim 11:11

Any object that is susceptible to corpse uncleanness, though not susceptible to midras uncleanness, is still susceptible to negaim uncleanness. For instance: the sail of a ship, a curtain, the forehead band of a hair-net, the wrappings of scrolls, a coiled belt, the straps of a shoe or sandal that are at least as wide as a split bean, Behold these are susceptible to the uncleanness of negaim. A thick cloak on which a nega appeared: Rabbi Eliezer ben Jacob says: unless it appears on the texture and on the stuffing. A skin bottle or a shepherd's leather wallet are inspected in the position in which they are used, and a nega may effectively spread from its inner side to its outer side and from its outer side to its inner side.

Mishnah Negaim 13:12

If he enters a synagogue, a partition ten handbreadths high and four cubits wide must be made for him. He should enter first and come out last. Any vessel that affords protection by having a tightly fitting cover in the tent of a corpse affords protection by a tightly fitting cover in the house of one afflicted by a nega, And whatsoever affords protection when covered in the tent of a corpse affords protection when covered in the house of one afflicted with a nega, the words of Rabbi Meir. Rabbi Yose says: any vessel that affords protection by having a tightly fitting cover in the tent of a corpse affords protection when covered in the house of one afflicted with a nega; and whatsoever affords protection when covered in the tent of a corpse remains clean even when uncovered in a leprous house.

Mishnah Parah 10:1

Any object that is susceptible to midras uncleanness is for the purpose of the hatat waters deemed to have madaf uncleanness, whether it was otherwise unclean or clean. A person too is subject to the same rule. Any object that is susceptible to corpse uncleanness, whether it is otherwise unclean or clean: Rabbi Eliezer says: it does not have madaf uncleanness. Rabbi Joshua says: it has madaf uncleanness; And the sages say: that which was unclean has madaf uncleanness, and that which was clean does not have madaf uncleanness.

Mishnah Tahorot 2:1

A woman who was preserving vegetables in a pot and touched a leaf outside the pot on a dry spot, even though the leaf had an egg's bulk of volume, it alone becomes unclean while all the rest remains clean. If she touched it at a wet spot: If there was an egg's bulk in the leaf, everything becomes unclean. If there was not an egg's bulk in it, it alone becomes unclean but all the rest remains clean. If it is returned into the pot, everything becomes unclean. If the woman was unclean due to contact with one who had corpse uncleanness, and she touched the leaf either at a wet spot or at a dry spot: If there was an egg's bulk in the leaf, everything becomes unclean; If there was not an egg's bulk in it, it alone becomes unclean but all the rest remains clean. If a woman who was a tevulat yom emptied out the pot with unwashed hands, and she observed some liquid on her hands, and it is uncertain whether it was splashed from the pot or whether a stalk had touched her hands, the vegetables are invalid but the pot remains clean.
