One who dismantles a bed in order that he might immerse it and [while doing so] touches the ropes remains clean. When does the rope begin to constitute a connective with the bed? As soon as three rows of meshes of it have been knotted. And [if another rope was tied to this one] and a person touches it: If from the knot inwards he becomes unclean; But if from the knot outwards he remains clean. As to the loose ends of the knot, any one that touches that part which is needed for it becomes unclean. And how much is needed for it? Rabbi Judah says: three fingerbreadths.

If a part of a mattress hangs over, it is unclean whatever its length, the words of Rabbi Meir. Rabbi Yose says: only that which is shorter than ten handbreadths. The remnant of a mattress remains unclean if the length is at least seven handbreadths from which a donkey's covering can be made.

If a zav was carried on a bed and on its mattress, the latter causes an uncleanness of two grades and an unfitness of one grade, the words of Rabbi Meir. Rabbi Yose says: if a zav was carried on a bed and on its mattress the part that is shorter than ten handbreadths causes an uncleanness of two grades and an unfitness of one grade, but that which is over the ten handbreadths causes only an uncleanness of one grade and an unfitness of one grade. If he was carried on the mattress, [on the overhanging part] that was shorter than ten handbreadths, it becomes unclean, but if on the part that was longer than ten handbreadths it remains clean.

If around a bed that had contracted midras uncleanness one wrapped a mattress, the whole becomes subject to midras uncleanness. If it was removed, the bed remains subject to midras uncleanness but the mattress is unclean only from contact with midras. If around a bed that had contracted seven-day uncleanness one wrapped a mattress, the whole becomes subject to seven-day uncleanness. If it was removed, the bed remains subject to seven-day uncleanness but the mattress is unclean until the evening. If the bed was subject to evening uncleanness and around it he wrapped a mattress, the whole becomes subject to evening uncleanness; If it was removed, the bed remains subject to evening uncleanness but the mattress becomes clean.

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.

A box whose opening is at the top is susceptible to corpse uncleanness. If a piece fell out above it is still susceptible to corpse uncleanness. If it was damaged below, it becomes clean. The compartments within it remain unclean and are not regarded as a connected to it.

A shepherd's bag which the pocket within it was damaged retains its uncleanness and is not regarded as a connected to it. A skin whose testicle bags serve also as receptacles and they were damaged, they become clean, since they will no longer serve their original purpose.

A box whose opening is at the side is susceptible to both midras uncleanness and corpse uncleanness. Rabbi Yose said: When does this apply? When it is less than ten handbreadths in height or when it does not have a rim one handbreadth deep. If it was damaged above it is still susceptible to corpse uncleanness. If it was damaged below: Rabbi Meir rules that it is susceptible to uncleanness. But the sages rule that it is clean because if the primary function ceases the secondary one also ceases.

A dung-basket that was so damaged that it will not hold pomegranates: Rabbi Meir says is still susceptible to uncleanness, But the sages say that it is clean because if the primary function ceases the secondary one also ceases.
