Leviticus 11:31-38

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

32Whatever falls on them when they are dead will become unclean, whether it is any vessel of wood, or clothing, or skin, or sackcloth. Whatever vessel it is, with which any work is done, it must be put into water, and it will be unclean until the evening, then it will be clean.

33“Now if any of them falls into a clay pot, everything that is in it will become unclean, and you are to break it.

34Any food that may be eaten but has water on it from such a pot will become unclean. Also any drink that may be drunk in any such pot will become unclean.

35Everything on which part of their carcass falls will become unclean. An oven or stove for pots is to be broken in pieces. They are unclean and will be unclean to you.

36Nevertheless, a spring or a cistern for collecting water will be clean, though anyone who touches their carcass will become unclean.

37If part of a carcass falls on any seed for sowing that has yet to be sown, it is clean.

38But if water is put on the seed, and part of a carcass falls on it, it is unclean to you.
