'Purification' in the Bible

She will continue in purification from her bleeding for 33 days. She must not touch any holy thing or go into the sanctuary until completing her days of purification.

But if she gives birth to a female child, she will be unclean for two weeks as she is during her menstrual impurity. She will continue in purification from her bleeding for 66 days.

“When her days of purification are complete, whether for a son or daughter, she is to bring to the priest at the entrance to the tent of meeting a year-old male lamb for a burnt offering, and a young pigeon or a turtledove for a sin offering.

But the goat chosen by lot for azazel is to be presented alive before the Lord to make purification with it by sending it into the wilderness for azazel.
