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.
(non occ.) The Lord had taught us above that our neighbour’s wife was not to be coveted, He now proceeds to teach that our own wife is not to be put away.
