'Impurity' in the Bible

“Tell the Israelites: When a woman becomes pregnant and gives birth to a male child, she will be unclean seven days, as she is during the days of her menstrual impurity.

But if she gives birth to a female child, she will be unclean for two weeks as she is during her menstrual impurity. She will continue in purification from her bleeding for 66 days.

Any bed she lies on during the days of her discharge will be like her bed during menstrual impurity; any furniture she sits on will be unclean as in her menstrual period.

“You are not to come near a woman during her menstrual impurity to have sexual intercourse with her.

If a man marries his brother’s wife, it is impurity. He has shamed his brother; they will be childless.
