Matthew 5:32

32. But I say unto you Our Lord has quoted the words of Moses, and seems to oppose them with this but. Yet it is not the law in its purity which he quotes and corrects. He does not oppose Moses. But what he does oppose and correct is that law as it is uttered by the mouth of those who quote it for licentious purposes, making it the means of all that dissoluteness described in our note on Matthew 5:31. That licentiousness he corrects by limiting divorce to cases of adultery; or rather he restores this provision as the true intent of the law of Moses. Causeth her to commit adultery The dismissing a wife for other cause than unfaithfulness, did not dissolve the marriage. Yet, as by unlawful custom she could marry again, in such cases the husband dismissing her occasioned the adultery. Whosoever shall marry her that is divorced That is, thus unlawfully divorced, and so not divorced at all. Committeth adultery By marrying her who is still bound by an unbroken marriage tie to her former husband, who has unlawfully dismissed her.
