Bede the Venerable
Catena Aurea · Matthäusevangelium 2
And when they were departed, behold, the angel of the Lord appeareth to Joseph in a dream, saying, Arise, and take the young Child and His mother, and flee into Egypt, and be thou there until I bring thee word; for Herod will seek the young Child to destroy Him. When he arose, he took the young Child and His mother by night, and departed into Egypt: And was there until the death of Herod: that it might be fulfilled which was spoken of the Lord by the prophet, saying, Out of Egypt have I called my Son.
(Hom. in. Nat. Innocent.) The flight into Egypt signifies that the elect are often by the wickedness of the bad driven from their homes, or sentenced to banishment. Thus He, who, we shall see below, gave thecommand to His own, When they shall persecute you in one city, flee ye to another, first practised what He enjoined, as a man flying before the face of man on earth. He whom but a little before a star had proclaimed to the Magi to be worshipped as from heaven.
