Leviticus 15:24-26

²⁴If a man copulateth with her in the time of her flowers, he shall be unclean seven days: and every bed on which he shall sleep shall be defiled.

²⁵The woman that hath an issue of blood many days out of her ordinary time, or that ceaseth not to flow after the monthly courses, as long as she is subject to this disease, shall be unclean, in the same manner as if she were in her flowers.

²⁶Every bed on which she sleepeth, and every vessel on which she sitteth, shall be defiled.
