Leviticus 15:13-18 - Purity Regulations For Male Bodily Discharges

13 And when he that has a discharge is cleansed of his discharge; then he shall number to himself seven days for his cleansing, and wash his clothes, and bathe his flesh in running water, and shall be clean. 14 And on the eighth day he shall take for him two turtledoves, or two young pigeons, and come before the LORD unto the door of the tabernacle of meeting, 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 the priest shall make an atonement for him before the LORD for his discharge.

16 And if any man's semen go out from him, then he shall wash all his flesh in water, and be unclean until the evening. 17 And every garment, and every skin, on which is the semen, shall be washed with water, and be unclean until the evening. 18 The woman also with whom man shall lie and have an emission of semen, they shall both bathe themselves in water, and be unclean until the evening.
