Leviticus 15:23-25

New Catholic Bible

²³ Whoever touches anything that was on her bed or on something upon which she sat shall be unclean until the evening. ²⁴ If any man lies with her so that her impurity is upon him, he shall be unclean for seven days and any bed upon which he lies shall be unclean.

²⁵ “ ‘If a woman has a discharge of blood for many days outside of the normal time of her impurity, or if it runs beyond the time of her impurity, then all the days when she has an unclean discharge shall be the same as the days of her menstrual impurity. She shall be unclean.
