Leviticus 15:1-15

And the LORD spoke to Moses and Aaron, saying, “Speak to the children of Israel, and say to them: ‘When any man has a discharge from his body, his discharge is unclean. 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. Every bed is unclean on which he who has the discharge lies, and everything on which he sits shall be unclean. And whoever touches his bed shall wash his clothes and bathe in water, and be unclean until evening. He who sits on anything on which he who has the discharge sat shall wash his clothes and bathe in water, and be unclean until evening. And he who touches the body of him who has the discharge shall wash his clothes and bathe in water, and be unclean until evening. If he who has the discharge spits on him who is clean, then he shall wash his clothes and bathe in water, and be unclean until evening. Any saddle on which he who has the discharge rides shall be unclean. Whoever touches anything that was under him shall be unclean until evening. He who carries any of those things shall wash his clothes and bathe in water, and be unclean until evening. And whomever the one who has the discharge touches, and has not rinsed his hands in water, he shall wash his clothes and bathe in water, and be unclean until evening. The vessel of earth that he who has the discharge touches shall be broken, and every vessel of wood shall be rinsed in water. ‘And when he who has a discharge is cleansed of his discharge, then he shall count for himself seven days for his cleansing, wash his clothes, and bathe his body in running water; then he shall be clean. On the eighth day he shall take for himself two turtledoves or two young pigeons, and come before the LORD, to the door of the tabernacle of meeting, and give them to the priest. Then the priest shall offer them, the one as a sin offering and the other as a burnt offering. So the priest shall make atonement for him before the LORD because of his discharge.
