What the Bible says about Mary's Purification
(From Forerunner Commentary)

Luke 2:22-24 Joseph and Mary left Bethlehem for Jerusalem shortly after Christ's birth. In accordance with God's laws, they needed to bring a sacrifice before God for Mary's purification (Leviticus 12:1-8). Also, they needed to dedicate Christ, as a firstborn, to God (Exodus 13:2; 22:29; Numbers 3:13; 8:16; 18:15-16).
