“And I say unto you, Whosoever shall put away his wife, except it be for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.”
King James Version (KJV)
19:9 And I say to you - I revoke that indulgence from this day, so that from henceforth, Whosoever, &c.
Mt 19:9 I say unto you. We have here Christ's law of divorce in contrast with that of Moses. Except [it be] for fornication. There is only one sufficient cause of divorce; that is, unfaithfulness to the marriage relation. Committeth adultery. Because he is married still to his former wife, who is still his wife in spite of the divorce; so, too, if any man marries the divorced woman, he marries another man's wife.
