Leviticus 11:31-36

³¹These are unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even.

³²And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherein any work is done, it must be put into water, and it shall be unclean until the even; so it shall be cleansed.

³³And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean; and ye shall break it.

³⁴Of all meat which may be eaten, that on which such water cometh shall be unclean: and all drink that may be drunk in every such vessel shall be unclean.

³⁵And every thing whereupon any part of their carcase falleth shall be unclean; whether it be oven, or ranges for pots, they shall be broken down: for they are unclean, and shall be unclean unto you.

³⁶Nevertheless a fountain or pit, wherein there is plenty of water, shall be clean: but that which toucheth their carcase shall be unclean.
