Leviticus [Pertaining to Levites] 15:24-26

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.

²⁶Every bed whereon she lies all the days of her discharge shall be to her as the bed of her period: and everything whereon she sits shall be unclean, as the uncleanness of her period.
