Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement: But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
For when Moses brought the children of Israel out of Egypt, they were indeed Hebrews in race, but Egyptians in manners. And it was caused by the Gentile manners that the husbandhated the wife; and if he was not permitted to put her away, he was ready either to kill her or ill-treat her. Moses therefore suffered the bill of divorcement, not because it was a good practice in itself, but was the prevention of a worse evil.
