Leviticus 12:2-4

2Speak unto the children of Israel, saying, If a woman conceive seed, and bear a male, then she shall be unclean seven days; as in the days of the separation of her infirmity shall she be unclean.

3And on the eighth day shall the flesh of his foreskin be circumcised.

4And she shall continue thirty-three days in the blood of her cleansing; no holy thing shall she touch, nor come into the sanctuary, until the days of her cleansing are fulfilled.
