Leviticus 11:35-38

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

³⁶Nevertheless, a fountain, or pit, receptacles for water, shall be clean; but he that toucheth their carcass shall be unclean.

³⁷And if any part of their carcass fall upon any sowing-seed which hath been sown, it shall be clean.

³⁸But if any water be put upon the seed, and any part of their carcass fall thereon, it shall be unclean unto you.
