The beam of a comber’s balance scale is tamei, on account of [its] hooks. And [the beam of the balance scale] of householders, if it has hooks, it is tamei. Hooks [on the poles] of porters are tahor. But hooks [on the poles] of peddlers are tamei. R’ Yehudah says: [With regard to the hooks] of peddlers, that which is in front of him is tamei, but that which is behind him is tahor. The hooks of a dargash are tamei. But [the hooks] of bed poles are tahor. [The hook] of a chest is tamei. But [the hook] of a fish trap is tahor. [The hook] of a table is tamei. [But the hook] of a wooden candelabra is tahor. This is the general rule: Anything attached to that which is tamei is [itself] tamei. And anything attached to that which is tahor is [itself] tahor. [And regarding] all of these [hooks], each one on its own is tahor.
