Leviticus 12:2

“Say to the Israelites: ‘A woman who becomes pregnant and gives birth to a son will be ceremonially unclean for seven days, just as she is unclean during her monthly period.

“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.

“Give the following instructions to the people of Israel. If a woman becomes pregnant and gives birth to a son, she will be ceremonially unclean for seven days, just as she is unclean during her menstrual period.

“Speak to the Israelites, saying, ‘When a woman becomes pregnant and she gives birth to a male, then she shall be unclean seven days—as in the time of her menstrual bleeding, she shall become unclean.

Speak unto the children of Israel, saying, If a woman have conceived seed, and born a man child: then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.
