Leviticus 15:23-25

Christian Standard Bible

²³ If discharge is on the bed or the furniture she was sitting on, when he touches it he will be unclean until evening. ²⁴ If a man sleeps with her, and blood from her menstruation gets on him, he will be unclean for seven days, and every bed he lies on will become unclean.^(A)

²⁵ “When a woman has a discharge of her blood for many days, though it is not the time of her menstruation, or if she has a discharge beyond her period, she will be unclean all the days of her unclean discharge, as she is during the days of her menstruation.
