Leviticus 15:17

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

¹⁶And the man whose seed of copulation shall happen to go forth from him, shall then wash his whole body, and shall be unclean until evening.

— Leviticus 15:17 —

¹⁸And a woman, if a man shall lie with her with seed of copulation—they shall both bathe themselves in water and shall be unclean until evening.

¹⁹And the woman whosoever shall have an issue of blood, when her issue shall be in her body, shall be seven days in her separation; everyone that touches her shall be unclean until evening.
