Leviticus 15:13-18 - Purity Regulations For Male Bodily Discharges
13 "'When he that hath an issue is cleansed of his issue, let him number seven days after he is clean, and wash his clothes, and bathe his flesh in running water, and then he is clean. 14 And the eighth day let him take two turtle doves or two young pigeons, and come before the LORD unto the door of the tabernacle of witness, and give them unto the priest. 15 And the priest shall offer them: the one for a sin offering, and the other for a burnt offering: and make an atonement for him before the LORD, as concerning his issue.
16 "'If any man's seed depart from him in his sleep, he shall wash his flesh in water and be unclean until evening. 17 And all the clothes or furs whereon such seed chanceth shall be washed with water and be unclean unto the evening. 18 And if a woman lie with such a one, they shall wash themselves with water and be unclean until even.
