“‘You must not approach a woman in her menstrual impurity ¹  to have sexual intercourse with her.

and the priest is to make one a sin offering and the other a burnt offering. ¹  So the priest ²  is to make atonement for her before the Lord from her discharge of impurity.

“‘When a woman’s discharge of blood flows ¹  many days not at the time of her menstruation, or if it flows beyond the time of her menstruation, ²  all the days of her discharge of impurity will be like the days of her menstruation – she is unclean.
