Leviticus 15:14-16

Amplified Bible

¹⁴ On the eighth day he shall take two turtledoves or two young pigeons and come before the Lord to the doorway of the Tent of Meeting, and give them to the priest; ¹⁵ and the priest shall offer them, one as a sin offering and the other as a burnt offering. So the priest shall make atonement for the man before the Lord because of his discharge.

¹⁶ ‘Now if any man has a seminal emission, he shall wash all his body in water, and be unclean until evening.
