Leviticus 15:17

15 And 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.

16 And 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.

And every garment, and every skin, whereon is the seed of copulation, shall be washed with water, and be unclean until the even.

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

19 And 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.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
