Leviticus 15:18–28

¹⁸If a man sleeps with a woman and has an emission of semen, both of them are to bathe with water, and they will remain unclean until evening.^d

¹⁹“When a woman has a discharge, and it consists of blood from her body, she will be unclean because of her menstruation^e for seven days. Everyone who touches her will be unclean until evening. ²⁰Anything she lies on during her menstruation will become unclean, and anything she sits on will become unclean. ²¹Everyone who touches her bed is to wash his clothes and bathe with water, and he will remain unclean until evening. ²²Everyone who touches any furniture she was sitting on is to wash his clothes and bathe with water, and he will remain unclean until evening. ²³If discharge is on the bed or the furniture she was sitting on, when he touches it he will be unclean until evening. ²⁴If 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.^f

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. ²⁶Any bed she lies on during the days of her discharge will be like her bed during menstrual impurity; any furniture she sits on will be unclean as in her menstrual period. ²⁷Everyone who touches them will be unclean; he must wash his clothes and bathe with water, and he will remain unclean until evening. ²⁸When she is cured of her discharge, she is to count seven days, and after that she will be clean.^g
