Luke 2:22-23

And 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] [Lev 12:1-4] (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)” [Ex 13:1, 2, 12; Num 8:17]
