Leviticus 12:1-4

The LORD said to Moses, “Tell the people of Israel this: ‘If a woman gives birth to a son, she will become unclean for seven days, as she is unclean during her monthly period. On the eighth day the boy must be circumcised. Then it will be thirty-three days before she becomes clean from her loss of blood. She must not touch anything that is holy or enter the Holy Tent until her time of cleansing is finished.
