Leviticus [Pertaining to Levites] 15:22-25

²²Whoever touches anything that she sits on shall wash his clothes, and bathe himself in water, and be unclean until the evening.

²³If it is on the bed, or on anything whereon she sits, when he touches it, he shall be unclean until the evening.

²⁴“‘If any man lies with her, and her monthly flow is on him, he shall be unclean seven days; and every bed whereon he lies shall be unclean.

²⁵“‘If a woman has a discharge of her blood many days not in the time of her period, or if she has a discharge beyond the time of her period; all the days of the discharge of her uncleanness shall be as in the days of her period: she is unclean.
