Leviticus 11:36-38

New Catholic Bible

³⁶ But a spring or a cistern where water is stored will be clean. Whoever touches their carcasses shall be unclean. ³⁷ If any part of their carcasses falls upon seed for sowing, it will still be clean. ³⁸ But if water falls on the seed and part of their carcasses falls on it, it is unclean to you.
