Rambam - 3 Chapters a Day

The following rules apply when a person held one hand over a corpse and one hand over keilim or he touched a corpse and held his hand over keilim. If each of his hands cover a handbreadth of space, the keilim are impure. If they are smaller, they are pure.

Similarly, if there are two buildings near each other and there is a portion of a corpse the size of half an olive in each of them and a person inserted one hand into one building and the other into the second building, if each of his hands cover a handbreadth of space, he has joined the impurity together. Everything is considered as one ohel and he and the buildings are impure. If they are smaller, he does not join the impurity together.

When a person looks out from a window and leans over impurity, he conveys impurity to the house in which he is located. The entire house becomes impure. If he was lying on the doorstep, part of his body being in the house and part being outside the house and impurity was positioned above the portion outside the house, the house is impure, because a person is hollow and the upper portion of his body is a handbreadth high. Since impurity was held over him, it is as if he stood over it and he conveys the impurity.

Similarly, if there was impurity within a house and pure people stood over the portion of a man lying outside, over the doorstep, they are impure. The rationale is that he is considered as if he is covering impurity and a person conveys impurity, but does not intervene against it, as we explained.

The following rules apply when the people carrying a corpse passed under an exedra, one of them closed the door to a house and locked it with a key so that the house would not become impure or if there was a person inside or outside who closed the door. If the door could stand closed by itself, the house is pure. If not, the house is impure. The rationale is that in the latter situation, it was the person who intervened in the face of ritual impurity. As we explained, a person and keilim convey ritual impurity and do not intervene in the face of it.

When an oven standing in a house has a dome-shaped opening that extends outside, if people carrying a corpse carried it over the opening that extends outside, the oven is impure, but the house is pure. The rationale is that the oven is not upraised above the ground so that it would bring impurity to the house.

When an oversized closet standing in an entrance opens to the outside and there is impurity in it, the house is pure. When there is impurity in the house, what is in the closet is impure, because it is open in the entrance and it is the nature of impurity to depart and not to enter. If its drawer was extended behind it, projecting less than a handbreadth, and could not be separated from the closet and there was impurity there opposite the boards of the roof of the house, the house is pure. The rationale is that even though it projects outward, it cannot be separated and it does not extend a handbreadth. This applies provided it is a handbreadth by a handbreadth and a handbreadth in height. If the drawer does not have an empty space of a handbreadth, the impurity is considered as flush within the house and the house is impure.

If the closet was standing in the house itself and there was impurity in it or in a chest within it, even though there is not an opening of a handbreadth through which the impurity could depart, the house is impure. If there is impurity in the house, everything in the closet is pure. The rationale is that the nature of impurity is to depart and not to enter.

If there are keilim between the closet and the ground, between it and the wall, or between it and the ceiling, they are impure if there is a handbreadth of empty space there. If not, they are pure, because we considered it as if the beams of the ceiling descend and close the space between it and the closet.

If there is impurity under the closet, between it and the earth, between it and the boards of the ceilings, or between it and the wall, the house is impure whether there is an open space of a handbreadth or not.

If the closet was standing under the open air and there was impurity in it, the keilim within the breadth of its walls are pure. If there is impurity within the breadth of its walls, the keilim inside of it are pure.

All the slanted walls of tents are considered as the tents themselves.

What is implied? When a tent slants downward and ends within a fingerbreadth of the ground and there is impurity in the tent, the keilim under the slanted side are impure. If there is impurity under the slanted wall, the keilim in the tent are impure.

If there is impurity within the slanted wall, one who touches its inner side contracts impurity that lasts a week. One who touches its outer side contracts impurity that lasts until the evening, for the outer side of the slanting wall is considered as a k'li that touches a tent that has become impure.

If there is impurity on the outer side of the slanted wall, one who touches its outer side contracts impurity that lasts a week. One who touches the inner side of the slanting wall contracts impurity that lasts until the evening.

If there was half an olive-sized portion of a corpse inside the tent and half behind it, one who touches it - whether from inside or outside - contracts impurity that lasts until the evening. The tent itself contracts impurity that lasts for seven days.

If the edges of the tent were spread out on the ground and there was impurity on the ground under an edge of the tent spread out or above it, the impurity pierces through and ascends, pierces through and descends.

The following rules apply with regard to a beehive-like container lying on the ground, in the entrance of a building with its opening facing the outside and an olive-sized portion of a corpse under or on top of the portion outside the building. Whatever is directly under or above the olive-sized portion below or above the container is impure. Whatever is in its inner space is pure except a k'li that is directly above or below the impurity. The building is pure.

If there is impurity in the building, only the building is impure, but keilim that are in the container or under it or above it outside of the building are pure. If there was impurity in the container, everything is impure, i.e., everything in the building and everything in the container, everything above it and everything below it that is opposite the impurity, as we explained.

If the container was raised a handbreadth above the ground and there was impurity under it, in the building, or above it, everything is impure, i.e., everything in the building, everything below it and everything above it. Whatever is in its inner space, by contrast, is pure except a k'li that is directly above or below the impurity. If there was impurity in the container, everything is impure, i.e., everything in the container and everything in the building, everything below it and everything above it. The rationale is that keilim or people who become an ohel over impurity or who have impurity above them convey impurity and do not intervene in the face of it, as we explained.

When does the above apply? When the container is a k'li and hollow. Different laws apply, however, if it was damaged and broken open and the open portion was plugged with straw and thus it is not considered as a k'li, or it was filled with straw so there was not an empty space of a handbreadth by a handbreadth and a handbreadth high, but instead, it was stuffed and there was not an empty space of a handbreadth in one place. If it was a handbreadth raised above the ground and there was impurity under it or in the building, the building and all the space under it are impure, because everything constitutes one ohel. Its inner space and anything on top of it on the outside of the building are pure, because it is considered an ohel of wood and it is not a container. If there was impurity inside of it, only what is inside of it is impure. If the impurity was above it, the space above it until the heavens is impure.

If such a container was placed on the ground, it opened to the outside, and an olive-sized portion of a corpse was under it, the space under it until the depths is impure. If the impurity was above it, the space above it until the heavens is impure. If there was impurity in the building, only the building is impure. If there is impurity within the container, only its inner space is impure.

When a beehive-like container is lying on the ground in the entrance to a building, it opens up to the inside of the building, it is intact and hollow and there is an olive-sized portion of a corpse below it or above it, everything that is directly below the olive-sized portion of impurity or over it is impure. Everything that is in its inner space is pure except those keilim that are directly above or directly below the impurity and the building is pure.

If it was raised a handbreadth above the ground and there was impurity under it, in it, above it, or in the building, everything is impure: everything that is in the building and everything under it, because it and the building constitute one ohel.

If it was damaged and broken opened and the open portion was plugged with straw or stuffed, was raised a handbreadth above the ground and there was impurity under it, in the building, or in it, everything is impure except the articles above it. If the impurity was above it, the space above the impurity until the heavens is impure, but its inner space is pure and the space under it, the building, and everything in them is pure. Since it is not a k'li, it intervenes in the face of impurity.

If such a container was placed on the ground, it opened to the inside, and an olive-sized portion of a corpse was under it, the space under it until the depths is impure. If [the impurity] was above it, the space above it until the heavens is impure. If there was impurity within it or within the building, its inner space and the building are impure.

The following laws apply when there is a beehive-like container inside a building, it fills the entire height of the building, its opening is positioned toward the ceiling of the building, and it reaches the ceiling so that there is less than a handbreadth of space between it and the ceiling. If there is impurity in it, the building is impure. If there is impurity in the building, its contents are pure. The rationale is that when there is less than a handbreadth of open space, it is the nature of impurity to depart towards the building, but not to enter the container.

This law applies whether the container was standing upright or leaning on its side, with its opening to the wall and there was less than a handbreadth between it and the wall, whether there was one beehive-like container or two beehive-like containers, one above the other, and there was not a handbreadth of empty space between the upper container and the ceiling or the upper container and the wall.

When such a container was standing in the entrance to a building with its opening facing upward and there was less than a handbreadth between it and the lintel, if there is impurity in it, the building is pure. If there is impurity in the building, the contents of the container are impure. The rationale is that it is the nature of impurity to depart and not to enter.

The following laws apply when there is a hollow beehive-like container that is intact and resting on its side in the open and there is an olive-sized portion of a corpse below it or above it. Anything that is directly above or directly below the olive-size portion is impure. Whatever is within its inner space, is pure except what is directly above or below the impurity. Whatever is not directly above or below the impurity inside the container is pure. If there is impurity inside of it, everything is impure: everything inside of it and everything below the container or above it that is directly above or below the impurity.

If it was raised a handbreadth above the ground and there was impurity under it or above it, everything that is below it and everything that is above it is impure, but everything that is inside of it is pure except a k'li that is directly above or below the impurity.

If there is impurity inside of it, everything is impure, everything inside of it, everything below it, and everything resting upon it from above. The rationale is that keilim convey ritual impurity, but do not intervene in the face of it, as we explained. Accordingly, if this beehive-like container that was lying on the earth was damaged and then plugged with straw or it is an oversized wooden container and there is an olive-sized portion from a corpse under it, anything below it until the depths is impure. If the impurity is on top of it, anything above it until the heavens is impure. If the impurity is inside of it, only the keilim inside of it are impure.

If [such] a container was raised a handbreadth above the earth and there was impurity under it, the space beneath it alone is impure. If [the impurity] was inside of it, only its inner space is impure. If [the impurity] was on top of it, the space above [the impurity] until the heavens is impure. We have already explained that an oversized wooden container is considered as an ohel and not as a k’li. Therefore, it intervenes in the face [of impurity].

When an intact beehive-like container was resting on its base in the open space and there was impurity under it, inside of it, or on top of it, the impurity pierces through and ascends and pierces through and descends. If, however, it was raised a handbreadth above the ground, covered, or standing upside down and there was impurity below it, in it, or above it, everything is impure: everything inside of it, everything below it, everything above it if the impurity was below it, for a k'li conveys ritual impurity and does not intervene in the face of it, as we explained.

Accordingly, if the container was damaged and plugged with straw and there is impurity under it, in it, or above it, the impurity pierces through and ascends and pierces through and descends. If it was raised a handbreadth above the ground and there was impurity below it, the space below it alone is impure. If the impurity was inside of it or on top of it, anything above it until the heavens is impure, but the keilim under it are pure, because it is a ohel and intervenes.

If there is a camel standing in the open space and there was impurity below it, the keilim above it are pure. If there is impurity above it, the keilim under it are pure. If it was lying down and there was impurity under it, the impurity pierces through and ascends and pierces through and descends. Similarly, if there was impurity flush under its foot or above its foot, the impurity pierces through and ascends and pierces through and descends.

We already explained in Hilchot Nizirut that if a nazirite and an olive-size portion of a corpse were both under a camel, a bed, or another similar k'li, even though he contracts impurity that lasts seven days, he does not shave. From this, we can derive that all of the impurity mentioned with regard to an ohel created by a person, an animal, or a k'li have their source in the words of the Sages. Some of them are part of the Oral Tradition and others are decrees and safeguards. Therefore a nazirite does not shave because of any of these impurities and one is not liable for karet for entering the Temple or partaking of consecrated food. All of the statements regarding the impurity conveyed in this manner are relevant only with regard to the ritual impurity of terumah and sacrificial foods, as we explained.

There are three conditions that protect an entity located under the same ohel as a corpse from contracting impurity: a sealed covering, an ohel, and the fact that something was swallowed. Being swallowed prevents pure entities from contracting impurity and prevents impurity that was swallowed from departing and spreading that impurity. In contrast, a sealed cover and an ohel prevent pure entities from contracting impurity, but they do not prevent the impurity from departing and causing other entities to become impure.

What is implied? If there is a container that is sealed in a house that is impure, everything in the container is pure. Similarly, if there is an ohel in such a house, all of the keilim in that ohel are pure. If, however, there was an olive-sized portion from a corpse placed in containers that were sealed close and then they were brought into a house, the house is impure. Similarly, if there was one ohel inside another ohel and an olive-sized portion of a corpse in the inner ohel, all of the keilim in the outer ohel are impure.

In contrast, when entities are swallowed, pure articles are prevented from contracting impurity and impurity is prevented from spreading.

What is implied? When a dog ate the flesh of a human corpse and entered a house, the house is pure. When a ring was swallowed, even by a person, and then the person who swallowed it entered an ohel where a corpse was located, even though the person contracts the impurity that lasts seven days, the ring remains pure. Similarly, the fact that an entity was swallowed by a beast, a domesticated animal, a fowl, or a fish prevents it from contracting impurity as long as they are alive. If, however, they die and the flesh of a human corpse or keilim are in their intestines, it is as if these articles were not swallowed.

If the majority of one of a fowl's determining signs for ritual slaughter was slit or the majority of both an animal's signs were slit, even though the living beings were still in their death throes, they are considered as dead. They no longer protect the keilim that are swallowed in their intestines, nor do they prevent impurity that is in their intestines from spreading outward and imparting impurity.

How long may the impurity remain in their intestines and still impart impurity when they die? For a dog three full days, i.e., three twenty-four hour periods. For other wild beasts, domesticated animals, fowl, or fish, one full day.

When does the above apply? When the flesh of the corpse remains in their intestines. If, however, a wolf swallows a baby and then expels it through its anus, the flesh is pure, but the bones are impure.

Entities that are swallowed are protected from impurity only in the digestive organs of a living creature, as we explained. Those, however, which are concealed in the body of a k'li or a stone are not protected.

What is implied? If there is a spindle in which a metal hook was concealed, into which the iron point was driven, or a brick in which a ring was found that were brought into an ohel in which a corpse was found, the articles are impure even though they are not visible and they are covered. The rationale is that articles encompassed by keilim are protected from impurity only by a sealed cover.

Similarly, if there was a pin or a ring covered in the clay used to reinforce an oven and the oven became impure because it was in an ohel where a corpse was located or a dead crawling animal fell into its inner space, the keilim in the clay become impure. If, however, the oven was sealed close, since the oven itself is pure, the keilim that are covered up by the clay on top of it are also pure.

Similarly, if a jug is sealed closed and there is a needle or a ring in the clay sealing at its side, they are impure, and they are not saved in an ohel where a corpse was located. If they were in the sealing of the jug over its opening and they could be seen from the inside of the jug, but do not enter its inner space, they are pure. If they enter its inner space, they are impure. The rationale is that an earthenware container that is sealed close does not protect the keilim that are inside of it, as will be explained. If there is a layer of clay, even as thin as a garlic shell under them, they are pure, even though they project into the inner space of the jug.

All keilim that are embedded in the earth of a house are impure and they are not protected. The rationale is that the earth of an ohel has the same status of the ohel itself until the very depths of the earth. This does not apply with regard to its walls, as will be explained.

What is implied? If there is impurity in a house and there are keilim embedded in its earth, even if they are deeper than 100 cubits, they are impure. If, however, there is a handbreadth by a handbreadth by a handbreadth of empty space in their place, they are pure, because it is as if they are in another ohel. To what can the matter be compared? To a loft that is built over a house. If there is impurity in the loft, the house is pure.

Similarly, if one divided a house with a partition that runs parallel to the ground and there was impurity between the partition and the earth, the keilim that are in the house above the partition are impure, because an ohel does not prevent the spread of impurity, as we explained. If there was impurity above the partition, the keilim between the partition and the earth are pure, because the ohel protects them. If there is not a space of a handbreadth between the partition and the ground, the keilim are considered as if they are embedded in the earth of the house and they are impure.

The following laws apply when there is a covered drain extending under a house and the drain is a handbreadth by a handbreadth by a handbreadth and its opening outside the house is a cubic handbreadth in size. If there is impurity in the drainage channel, the house is pure. If there is impurity in the house, the contents of the drainage channel are pure.

If the drain was a cubic handbreadth in size, but its opening on the outside was not a cubic handbreadth in size and there was impurity in it, the house is impure. If there is impurity in the house, the contents of the drainage channel are pure. The rationale is that it is not the way of impurity to enter a secondary entity like a drain.

If the drain was not a cubic handbreadth in size and its opening on the outside was not a cubic handbreadth in size and there was impurity in it, the house is impure. It is as if the impurity is in the house. If there is impurity in the house, the contents of the drain are impure. The rationale is that they are considered like keilim buried in the earth and the earth of a house has the same status as the house itself until the very depths.

When there are two jugs, each containing half of an olive-sized portion of a corpse and each is sealed close, placed within a house, they are pure, because a partial measure of impurity does not impart impurity. The house is impure, because there is an olive-sized portion of a corpse in the house and a sealed cover does not prevent the spread of impurity outward. The jugs do not become impure because of the house, because they are sealed close. If one of the jugs are open, it and the house are impure and the other jug is pure.

Similarly, if there are two rooms open to each other and to the main room of a house and there is half of an olive-sized portion of a corpse in the inner room or the middle room and half of an olive-sized portion of a corpse in the outer room, the outer room is impure. The inner room and the middle room are pure. If there is half of an olive-sized portion of a corpse in the inner room and half of an olive-sized portion of a corpse in the middle room, the inner room is pure. The middle and the outer rooms are impure, because it is the way of impurity to depart and not to enter.
