What is different considering the transferred impurity when a man lies with a woman during her menstrual impurity compared to the other circumstances (Leviticus 15:21–23)?
This verse involves a man having sexual intercourse with a woman during her menstrual impurity. If this were to happen, the man would become ceremonially unclean for seven days.
24 And if any man lies with her and her menstrual impurity comes upon him, he shall be unclean seven days, and every bed on which he lies shall be unclean.
