Direct biblical statement
Luke 2:22–32
A light to the nations
22 And after the days of her purification, according to the law of Moses, were accomplished, they carried him to Jerusalem, to present him to the Lord:
23 As it is written in the law of the Lord: Every male opening the womb shall be called holy to the Lord:
24 And to offer a sacrifice, according as it is written in the law of the Lord, a pair of turtledoves or two young pigeons:
25 And behold there was a man in Jerusalem named Simeon: and this man was just and devout, waiting for the consolation of Israel. And the Holy Ghost was in him.
26 And he had received an answer from the Holy Ghost, that he should not see death before he had seen the Christ of the Lord.
27 And he came by the Spirit into the temple. And when his parents brought in the child Jesus, to do for him according to the custom of the law,
28 He also took him into his arms and blessed God and said
29 Now thou dost dismiss thy servant, O Lord, according to thy word in peace:
30 Because my eyes have seen thy salvation,
31 Which thou hast prepared before the face of all peoples:
32 A light to the revelation of the Gentiles and the glory of thy people Israel.

Why this matters
Mary and Joseph bring Jesus to the Temple according to the law. Simeon recognizes God’s salvation in Jesus, a light for the nations and glory for Israel.
