Leviticus 15:31-33

Living Bible

³¹ In this way you shall cleanse the people of Israel from their defilement, lest they die because of defiling my Tabernacle that is among them.”

³² This, then, is the law for the man who is defiled by a genital disease^[a] or by a seminal emission; ³³ and for a woman’s menstrual period; and for anyone who has sexual intercourse with her while she is in her period of defilement afterwards.
