Leviticus 11:32-34

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.
