Pseudo-Chrysostom
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.
He says not, ‘the Mother and her young Child,’ but, the young Child and His mother; for the Child was not born for the mother, but the mother prepared for the Child. How is this that the Son of God flies from the face of man? or who shall deliver from the enemy’s hand, if He Himself fears His enemies? First; He ought to observe, even in this, the law of that human nature which He took on Him; and human nature and infancy must flee before threatening power. Next, that Christians when persecution makes it necessary should not be ashamed to fly. But why into Egypt? The Lord, who keepeth not His anger for ever, remembered the woes He had brought upon Egypt, and therefore sent His Son thither, and gives it this sign of great reconciliation, that with this one remedy He might heal the ten plagues of Egypt, and the nation that had been the persecutor of this first-born people, might be the guardian of His first-born Son. As formerly they had cruelly tyrannized, now they might devoutly serve; nor go to the Red Sea to be drowned, but be called to the waters of baptism to receive life.
