Leviticus 15:22-24

New Revised Standard Version, Anglicised

²² Whoever touches anything upon which she sits shall wash his clothes, and bathe in water, and be unclean until the evening; ²³ whether it is the bed or anything upon which she sits, when he touches it he shall be unclean until the evening. ²⁴ If any man lies with her, and her impurity falls on him, he shall be unclean for seven days; and every bed on which he lies shall be unclean.
