'Menstruation' in the Bible

“When a woman has a discharge, and it consists of blood from her body, she will be unclean because of her menstruation for seven days. Everyone who touches her will be unclean until evening.

Anything she lies on during her menstruation will become unclean, and anything she sits on will become unclean.

If a man sleeps with her, and blood from her menstruation gets on him, he will be unclean for seven days, and every bed he lies on will become unclean.

“When a woman has a discharge of her blood for many days, though it is not the time of her menstruation, or if she has a discharge beyond her period, she will be unclean all the days of her unclean discharge, as she is during the days of her menstruation.
