Leviticus 11:35-38

³⁵And upon whatsoever thing any of these dead beasts shall fall, it shall be unclean: whether it be oven, or pots with feet, they shall be destroyed, and shall be unclean.

³⁶But fountains and cisterns, and all gatherings together of waters shall be clean. He that toucheth their carcasses shall be defiled.

³⁷If it fall upon seed corn, it shall not defile it.

³⁸But if any man pour water upon the seed, and afterwards it be touched by the carcasses, it shall be forthwith defiled.
