14 Who arose, and took the child and his mother by night, and retired into Egypt: and he was there until the death of Herod: 15 That it might be fulfilled which the Lord spoke by the prophet, saying: Out of Egypt have I called my son.
Augustine: Christ by going down thither brought back light to them that sat in darkness. He fled that he might enlighten them, not that he might escape his foes.
Jerome: When he takes the Child and His mother to go into Egypt, it is in the night and darkness, when to return into Judaea, the Gospel speaks of no light, no darkness.
Pseudo-Chrysostom: The straitness of every persecution may be called night – the relief from it in like manner, day.
Chrysostom: See how immediately on His birth the tyrant is furious against Him, and the mother with her Child is driven into foreign lands. So should you in the beginning of your spiritual career seem to have tribulation, you need not to be discouraged, but bear all things manfully, having this example.
Bede: 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 the command 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.
