b. Notwithstanding, being warned of God in a dream, he turned aside into the parts of Galilee: and he came and dwelt in a city called Nazareth; that it might be fulfilled which was spoken by the prophets, He shall be called a Nazarene.
So Joseph returned to his former city, which had also been Mary's home, Luke 1:26; Luke 2:4. Nazareth was a small city southwest of the Sea of Galilee, not far from Cana, on the one side, and from Mount Tabor, on the west. It was situated on the slope of a hill, and was surrounded by beautiful and grand scenery. It was here that Jesus lived until He entered upon His ministry, Luke 2:51; Luke 4:16; Matthew 3:13.
This reference of the evangelist to a fulfillment of Old Testament prophecy has ever caused difficulties, since there is no individual passage, with the exact contents as given, in the writings referred to. It is significant, however, that Matthew writes: "Which was spoken by the prophets," thus indicating a general type rather than an explicit text. The most plausible explanation: "Nazarene" or "man of Nazareth" contains the reference. For the name Nazareth is derived from a Hebrew root meaning a branch or tender offshoot. Thus the Messiah is called in Isaiah 11:1. And this passage is analogous to the expressions used in Isaiah 53:2; Isaiah 4:2; Jeremiah 23:5; Jeremiah 33:15; Zechariah 3:8; Zechariah 6:12, and to other descriptions of the humble appearance of the Messiah. See John 1:46. Others have suggested that the reference is to Judges 13:7. "It is with the prophetic references in the gospels as with songs without words. The composer has a certain scene or state of mind in his view, and writes under its inspiration. But you are not in his secret, and cannot tell when you hear the music what it means. But let the key be given, and immediately you find new meaning in the music. The prophecies are the music; the key is the history."
Summary. The Magi having been directed to Bethlehem by a special star and by prophetic direction, give to the Christ-child divine adoration, while the life of the Savior is preserved from the cruelty of Herod by divine interposition, which directs Joseph first to Egypt, then to Galilee.
