Luke 2:22-24

22And when the time for their purification came [that is, the mother’s purification and the baby’s dedication] according to the Law of Moses, they brought Him up to Jerusalem to present Him to the Lord [set apart as the Firstborn]

23(as it is written in the Law of the Lord, “Every firstborn male that opens the womb shall be called holy [set apart and dedicated] to the Lord)”

24and [they came also] to offer a sacrifice according to what is said in the Law of the Lord [to be appropriate for a family of modest means], “a pair of turtledoves or two young pigeons.”
