From the Treasury of Daily Prayer:

Thirty-two days after Jesus’ circumcision and seventy weeks after the announcement of John’s birth to Zechariah by the angel Gabriel, the Lord comes to His temple to fulfill the Torah (Luke 2:22-38). The days are indeed fulfilled with the presentation. Jesus’ parents keep the Torah and fulfill it by brining Jesus to His true home. Also, Jesus’ parents offer the alternative sacrifice of two turtledoves or two pigeons. Leviticus 12:8 allows this instead of a lamb (showing the poverty and humility of Joseph and Mary). Yet no lamb was necessary because already here at forty days old, Jesus is the Lamb brought to His temple for sacrifice. Simeon’s Nunc Dimittis is a beautiful example of the immediate response to this inauguration of God’s consolation and redemption in the Christ Child. Speaking to Mary, Simeon also prophesies about the destiny of the child.
