Leviticus 12:2-4 New King James Version (NKJV)
2 “Speak to the children of Israel, saying: ‘If a woman has conceived, and borne a male child, then she shall be [a]unclean seven days; as in the days of her customary impurity she shall be unclean. 3 And on the eighth day the flesh of his foreskin shall be circumcised. 4 She shall then continue in the blood of her purification thirty-three days. She shall not touch any [b]hallowed thing, nor come into the sanctuary until the days of her purification are fulfilled.
