¹⁷ Every garment and every leather on which there is semen shall be washed with water, and shall be unclean until evening. ¹⁸ If a man lies with a woman so that there is a seminal emission, they shall both bathe in water and be unclean until evening.

¹⁹ ‘When a woman has a discharge, if her bodily discharge is blood, she shall continue in her menstrual impurity for seven days; and whoever touches her shall be unclean until evening.
