A wooden chest: Beth Shammai says: it is measured on the inside; And Bet Hillel says: on the outside. Both agree that the thickness of the legs and the thickness of the rim are not included in the measurement. Rabbi Yose says: both agree that the thickness of the legs and the thickness of the rim are included in the measurement, but the space between them is not included. Rabbi Shimon Shezuri ruled: if the legs are one handbreadth high the space between them is not included in the measurement, otherwise it is included.

Its carriage: if it can be slipped off, is not regarded as connected, nor is it included in its measurement, nor does it afford protection together with it in the tent of a corpse, nor may it be drawn along on Shabbat if it contains money. If it cannot be slipped off, it is regarded as connected, it is included in its measurement, it affords protection together with it in the tent of a corpse, it may be drawn along on Shabbat even if it contains money. Its arched top, if it is fixed [to the box], is considered connected and is measured with it, but if it is not fixed it is not connected and is not measured with it. How is it measured? As an ox-head. Rabbi Judah says: if it cannot stand by itself it is clean.

If one of the legs was missing from a chest, a box or a cupboard, even though it is still capable of holding [things], it is clean, since it cannot hold [things] in the usual manner. But Rabbi Yose says: it is susceptible to impurity. The poles of a bed, its base, and [its] covering are clean. Only the bed itself and its rectangle [frame] are susceptible to uncleanness. The rectangle frames of the Levites are clean.

A bed frame that was put on props: Rabbi Meir and Rabbi Judah say it is susceptible to uncleanness. But Rabbi Yose and Rabbi Shimon say that it is clean. Rabbi Yose said: Why is this different from the rectangle frames of the Levites which are clean?

A bed that had contracted midras uncleanness: If a short side was removed and its two legs still remains it is unclean. But if a long side and two legs were removed it becomes clean. Rabbi Nehemiah says: it is unclean. If two props at opposite corners were cut off, or if two legs at opposite corners were cut off, or if the bed was reduced to a level of less than a handbreadth, it becomes clean.

A bed that had contracted midras impurity:If a long side of it was broken and then he repaired it, it still retains its midras impurity. If the second side was also broke and then he repaired it, it becomes pure from midras impurity but is unclean by virtue of contact with midras. If before one could manage to repair the first side the second one broke, the bed becomes clean.

If a [bed] leg that had contracted midras uncleanness was joined to a bed, all the bed contracts midras uncleanness. If it was subsequently taken off, it retains its midras uncleanness while the bed is unclean from contact with midras. If a bed leg that was subject to a seven-day uncleanness was joined to a bed, all the bed contracts seven-day uncleanness. If it was subsequently taken off it remains subject to seven-day uncleanness while the bed is only subject to evening-uncleanness. If a leg that was subject to evening uncleanness was joined to a bed, all the bed contracts evening uncleanness. If it was subsequently taken off it is still subject to evening uncleanness while the bed becomes clean. The same law applies also to the prong of a mattock.

A bed half of which was stolen or lost, or one which brothers or joint owners divided between themselves, becomes clean. If it was restored it is susceptible to uncleanness henceforth. A bed may contract uncleanness and be rendered clean when all its parts are bound together, the words of Rabbi Eliezer. But the sages say: it can contract uncleanness and is rendered clean in single parts.
