Leviticus 15:30-34

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

“And so you shall keep the sons of Israel separated from their uncleanness, so that they will not die in their uncleanness by their defiling My tabernacle that is among them.”

This is the law for the one with a discharge, and for the man who has a seminal emission so that he is unclean by it,

and for the woman who is ill because of menstrual impurity, and for the one who has a discharge, whether a male or a female, or a man who sleeps with an unclean woman.
