Leviticus 11:35-38

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

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

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

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