Leviticus 15:18-20

Darby Translation

¹⁸ And a woman with whom a man lieth with seed of copulation—they shall bathe in water, and be unclean until the even.

¹⁹ And if a woman have a flux, and her flux in her flesh be blood, she shall be seven days in her separation, and whoever toucheth her shall be unclean until the even.

²⁰ And everything that she lieth upon in her separation shall be unclean; and everything that she sitteth upon shall be unclean.
