Leviticus 11:31–38

³¹These shall be unclean unto you among all that crawl: whoever toucheth them when they are dead, shall be unclean until the even. ³²And on whatever any of them when they are dead doth fall, it shall be unclean; all vessels of wood, or garment, or skin, or sack, every vessel wherewith work is done—it shall be put into water, and be unclean until the even; then shall it be clean. ³³And every earthen vessel into which any of them falleth—whatever is in it shall be unclean; and ye shall break it. ³⁴All food that is eaten on which such water hath come shall be unclean; and all drink that is drunk shall be unclean, in every such vessel. ³⁵And everything where upon any part of their carcase falleth shall be unclean; oven and hearth shall be broken down: they are unclean, and shall be unclean unto you. ³⁶Nevertheless, a spring or a well, a quantity of water, shall be clean. But he that toucheth their carcase shall be unclean. ³⁷And if any part of their carcase fall upon any sowing-seed which is to be sown, it shall be clean; ³⁸but if water have been put on the seed, and any part of their carcase fall thereon, it shall be unclean unto you.
