Leviticus 11:36-38

New Revised Standard Version Catholic Edition

³⁶ But a spring or a cistern holding water shall be clean, while whatever touches the carcass in it shall be unclean. ³⁷ If any part of their carcass falls upon any seed set aside for sowing, it is clean; ³⁸ but if water is put on the seed and any part of their carcass falls on it, it is unclean for you.
