Leviticus 11:32-34

32And upon whatever any of them, when they are dead, doth fall, it shall be unclean; whether it is any vessel of wood, or raiment, or skin, or sack, whatever vessel it is, in which any work is done, it must be put into water, and it shall be unclean until the evening; so it shall be cleansed. 33And every earthen vessel, into which any of them falleth, whatever is in it shall be unclean; and ye shall break it. 34Of all food 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.
