Leviticus 12:2-5

Speak unto the children of Israel, saying, If a woman conceive seed, and bear a man-child, then she shall be unclean seven days; as in the days of the impurity of her sickness shall she be unclean. And in the eighth day the flesh of his foreskin shall be circumcised. And she shall continue in the blood of her purifying three and thirty days; she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled. But if she bear a maid-child, then she shall be unclean two weeks, as in her impurity; and she shall continue in the blood of her purifying threescore and six days.
