Leviticus 11:31-36

³¹Of all the animals that creep, these are the animals which will be unclean to you. Whoever touches them when they are dead will be unclean until evening.

³²If any of them dies and falls on anything, that thing will be unclean, whether it is made of wood, cloth, leather, or sackcloth. Whatever it is and whatever it is used for, it must be put into water; it will be unclean until evening. Then it will be clean.

³³For every clay pot into or onto which any unclean animal falls, whatever is in the pot will become unclean, and you must destroy that pot.

³⁴Any food that could be eaten but has water on it from such a pot is unclean. Any liquid that is for drinking from such a pot is unclean.

³⁵Anything that one of their carcasses falls on becomes unclean; if it is an oven or small stove, it must be broken to pieces. They are unclean and they must remain unclean to you.

³⁶A spring or cistern for collecting water remains clean; but anyone who touches their carcass is unclean.
