Leviticus 15:17

¹⁵And the priest shall offer them, the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for him before the LORD for his issue.

¹⁶And if any man’s seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even.

¹⁸The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the even.

¹⁹And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even.
