Leviticus 15:14-18

Then on the eighth day he shall take for himself two turtledoves or two young doves, and come before the Lord to the doorway of the tent of meeting and give them to the priest;

and the priest shall offer them, one as a sin offering and the other as a burnt offering. So the priest shall make atonement on his behalf before the Lord because of his discharge.

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

As for any garment or any leather on which there is a seminal emission, it shall be washed with water and be unclean until evening.

If a man sleeps with a woman so that there is a seminal emission, they shall both bathe in water and be unclean until evening.
