Leviticus 11:31-38

31These are they which are unclean to you among all that creep: whosoever doth touch them, when they are 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, wherewith any work is done, it must be put into water, and it shall be unclean until the even; then shall it be clean. 33And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean, and it ye shall break. 34All food therein which may be eaten, that on which 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 carcass falleth shall be unclean; whether oven, or range for pots, it shall be broken in pieces: they are unclean, and shall be unclean unto you. 36Nevertheless a fountain or a pit wherein is a gathering of water shall be clean: but that which toucheth their carcass shall be unclean. 37And if aught of their carcass fall upon any sowing seed which is to be sown, it is clean. 38But if water be put upon the seed, and aught of their carcass fall thereon, it is unclean unto you.
