Matthew 2:22

He heard that Archelaus did reign - Archelaus possessed a cruel and tyrannical disposition similar to his father. At one of the Passovers he caused 3,000 of the people to be put to death in the temple and city. For his crimes, after he had reigned 9 years, he was banished by Augustus, the Roman emperor, to Gaul, where he died. Knowing his character, and fearing that he would not be safe, Joseph hesitated about going there, and was directed by God to go to Galilee, a place of safety.

The parts of Galilee - The country of Galilee. At this time the land of Palestine was divided into three parts: Galilee, on the north; Samaria, in the middle; and Judea, on the south. Galilee was under the government of Herod Antipas, who was comparatively a mild prince, and in his dominions Joseph might find safety.
