2“Say to the Israelites, ‘A woman who becomes pregnant and gives birth to a son will be unclean for seven days, as she is during the days of her menstruation.
3And on the eighth day the flesh of the boy’s foreskin is to be circumcised.
4The woman shall continue in purification from her bleeding for thirty-three days. She must not touch anything sacred or go into the sanctuary until the days of her purification are complete.
5If, however, she gives birth to a daughter, the woman will be unclean for two weeks as she is during her menstruation. Then she must continue in purification from her bleeding for sixty-six days.
