²³ And if it be on her bed, or on any thing whereon she sitteth, when he toucheth it, he shall be tamei until the erev.

²⁴ And if any ish lie with her at all, and her niddah (menstrual flow) be upon him, he shall be tamei seven days; and all the bed whereon he lieth shall be tamei.

²⁵ And if an isha have a discharge of her dahm many days out of the time of her niddah, or if it run beyond the time of her niddah, all the days of the discharge of her tumah shall be as the days of her niddah; she shall be tamei.
