Leviticus 15:18–28

¹⁸If a man lies with a woman and has an emission of semen, both of them shall bathe in water and be unclean until the evening.^*

¹⁹“When a woman has a discharge of blood that is a menstrual discharge from her body, she shall be in her impurity for seven days, and whoever touches her shall be unclean until the evening.^{* 20}Everything upon which she lies during her impurity shall be unclean; everything also upon which she sits shall be unclean. ²¹Whoever touches her bed shall wash his clothes and bathe in water and be unclean until the evening.^{* 22}Whoever touches anything upon which she sits shall wash his clothes and bathe in water and be unclean until the evening; ²³whether it is the bed or anything upon which she sits, when he touches it he shall be unclean until the evening. ²⁴If any man lies with her and her impurity falls on him, he shall be unclean seven days, and every bed on which he lies shall be unclean.^*

²⁵“If a woman has a discharge of blood for many days, not at the time of her menstrual impurity, or if she has a discharge beyond the time of her menstrual impurity, all the days of the discharge she shall continue in uncleanness; as in the days of her impurity, she shall be unclean.^{* 26}Every bed on which she lies during all the days of her discharge shall be treated as the bed of her impurity, and everything on which she sits shall be unclean, as in the uncleanness of her impurity. ²⁷Whoever touches these things shall be unclean and shall wash his clothes and bathe in water and be unclean until the evening.^{* 28}If she is cleansed of her discharge, she shall count seven days, and after that she shall be clean.
