Leviticus 15:13-18 - Purity Regulations For Male Bodily Discharges
13 "'When he who has a discharge is cleansed of his discharge, then he shall count to himself seven days for his cleansing, and wash his clothes; and he shall bathe his flesh in running water, and shall be clean. 14 "'On the eighth day he shall take two turtledoves, or two young pigeons, and come before Yahweh to the door of the Tent of Meeting, and give them to the priest: 15 and the priest shall offer them, the one for a sin offering, and the other for a burnt offering. The priest shall make atonement for him before Yahweh for his discharge.
16 "'If any man has an emission of semen, then he shall bathe all his flesh in water, and be unclean until the evening. 17 Every garment, and every skin, whereon the semen is, shall be washed with water, and be unclean until the evening. 18 If a man lies with a woman and there is an emission of semen, they shall both bathe themselves in water, and be unclean until the evening.
