Leviticus 15:2-4

New King James Version

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. ⁴ Every bed is ^[a]unclean on which he who has the discharge lies, and everything on which he sits shall be unclean.
