^19-23 “When a woman has a discharge of blood, the impurity of her menstrual period lasts seven days. Anyone who touches her is unclean until evening. Everything on which she lies or sits during her period is unclean. Anyone who touches her bed or anything on which she sits must wash his clothes and bathe in water; he remains unclean until evening.

²⁴ “If a man sleeps with her and her menstrual blood gets on him, he is unclean for seven days and every bed on which he lies becomes unclean.
