Leviticus 15
13 Ref And when he that hath an issue is cleansed of his issue, then he shall number 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 Ref And on the eighth day he shall take to him two turtle-doves, or two young pigeons, and come before Jehovah unto the door of the tent of meeting, and give them unto the priest:
15 Ref and the priest shall offer them, the one for a sin-offering, and the other for a burnt-offering; and the priest shall make atonement for him before Jehovah for his issue.
16 Ref And if any man's seed of copulation go out from him, then he shall bathe all his flesh in water, and be unclean until the even.
