Leviticus [Pertaining to Levites] 11:35-38

³⁵Everything where part of their carcass falls shall be unclean; whether oven, or range for pots, it shall be broken in pieces: they are unclean, and shall be unclean to you.

³⁶Nevertheless a spring or a cistern in which water is gathered shall be clean: but that which touches their carcass shall be unclean.

³⁷If part of their carcass falls on any sowing seed which is to be sown, it is clean.

³⁸But if water is put on the seed, and part of their carcass falls on it, it is unclean to you.
