Return to Nazareth in Galilee.
v.19-20 An angel again appears to Joseph in a dream and tells him to return to Israel because Herod is dead. Josephus records the horrible death of Herod (Antiquities 17.vi.5).
v.21-22 Joseph took Jesus and Mary and returned to Israel. He learned that Archelaus was reining over Judea and was afraid since Archelaus was a brutal ruler like his father Herod. Being warned in a dream, he withdrew to the district of Galilee.
v.23 Mary, Joseph and Jesus settled in the town of Nazareth. This fulfilled the OT prophecy: “He shall be called a Nazarene.” Nazareth was a small village halfway between the Mediterranean Sea and the Sea of Galilee. According to Luke, Nazareth was the former home of Joseph and Mary (Lk 2:39).
