The Law Concerning Bodily Discharges

15 And the Lord spoke to Moses and Aaron, saying, ² “Speak to the children of Israel, and say to them: ^(A)‘When any man has a discharge from his body, his discharge is unclean. ³ And this shall be his uncleanness in regard to his discharge—whether his body runs with his discharge, or his body is stopped up by his discharge, it is his uncleanness.
