Pseudo-Chrysostom

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.
