Leviticus 15:24-26

Amplified Bible

²⁴ If a man actually lies with her so that her menstrual impurity is on him, he shall be unclean for seven days; and every bed on which he lies shall be unclean.

²⁵ ‘Now if a woman has a flow of blood for many days, not during the time of her menstruation, or if she has a discharge beyond that period, as long as the impure discharge continues she shall be as she is in the days of her [normal] menstrual impurity; she is unclean.^{(A) 26} Every bed on which she lies during the time of her discharge shall be to her like the bed of her menstrual impurity, and whatever she sits on shall be unclean, like the uncleanness of her monthly period.
