Leviticus 15:15-19

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.

‘When a woman has a discharge, if her discharge in her body is blood, she shall continue in her menstrual impurity for seven days; and whoever touches her shall be unclean until evening.
