Leviticus 15:17-19

Living Bible

¹⁷ Any clothing or bedding the semen spills on must be washed and remain ceremonially defiled until evening. ¹⁸ After sexual intercourse, the woman as well as the man must bathe, and they are ceremonially defiled until the next evening.

¹⁹ “Whenever a woman menstruates, she shall be in a state of ceremonial defilement for seven days afterwards, and during that time anyone touching her shall be defiled until evening.
