Leviticus 15:13-16

Thomson(i) 13 And when he is clean of his disorder, he shall reckon for himself seven days for his purification, and he shall wash his clothes, and wash his body with water, and he shall be clean. 14 And on the eighth day he shall take him two turtle doves, or two young pigeons, and bring them before the Lord, to the door of the tabernacle of the testimony, and give them to the priest. 15 And the priest shall offer one of them for a sin offering, and the other for a whole burnt offering. So shall the priest make atonement for him before the Lord, on the account of his efflux. 16 And if any man's seed go from him by copulation, he shall wash his whole body with water, and be unclean until evening.
