Leviticus 12:2 "Speak to the sons of Israel, saying: 'When a woman gives birth and bears a male child, then she shall be unclean for seven days, as in the days of her menstruation she shall be unclean.

Leviticus 15:24 'If a man actually lies with her so that her menstrual impurity is on him, he shall be unclean seven days, and every bed on which he lies shall be unclean.

Leviticus 20:18 If there is a man who lies with a menstruous woman and uncovers her nakedness, he has laid bare her flow, and she has exposed the flow of her blood; thus both of them shall be cut off from among their people. (NASB ©1995)
