Leviticus 15:24-27

²⁴If a man is coupled fleshly with her in the time of blood that cometh, or runneth, from her by months, he shall be unclean by seven days, and each bed in which he sleepeth shall be unclean.

²⁵A woman that suffereth in many days the flowing out of blood, not in the time of the months, either which woman ceaseth not to flow out blood after the blood of the months, shall be unclean as long as she shall be subject to this passion, as if she is in the time of the months.

²⁶Each bed in which she sleepeth, and whatever thing she sitteth upon, shall be unclean.

²⁷Whoever toucheth her shall wash his clothes, and he shall be washed in water, and shall be unclean till to eventide.
