'Period' in the Bible

does not eat pagan sacrifices on the mountains or pray to the idols of the house of Israel, does not defile his neighbor's wife, does not have sexual relations with a woman during her period,

They have sex with their father's wife within you; they violate women during their menstrual period within you.

"Son of man, when the house of Israel was living on their own land, they defiled it by their behavior and their deeds. In my sight their behavior was like the uncleanness of a woman having her monthly period.

When the prescribed period is over, on the eighth day and thereafter the priests will offer up on the altar your burnt offerings and your peace offerings; I will accept you, declares the sovereign Lord."

After a priest has become ceremonially clean, they must count off a period of seven days for him.
