Catena Aurea · Matthäusevangelium 2
And he arose, and took the young Child and His mother, and came into the land of Israel. But when he heard that Archelaus did reign in Judæa in the room of his father Herod, he was afraid to go thither: 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.
Joseph was not disobedient to the angelic warning, but he arose, and took the young Child and his mother, and came into the land of Israel. The Angel had not fixed the particular place, so that while Joseph hesitates, the Angel returns, and by the often visiting him confirms his obedience.
