But I say to you. Mark relates that this was spoken to the disciples apart, when they had come into the house; but Matthew, leaving out this circumstance, gives it as a part of the discourse, as the Evangelists frequently leave out some intermediate occurrence, because they reckon it enough to sum up the leading points. There is therefore no difference, except that the one explains the matter more distinctly than the other. The substance of it is: though the Law does not punish divorces, which are at variance with God's first institution, yet he is an adulterer who rejects his wife and takes another. For it is not in the power of a man to dissolve the engagement of marriage, which the Lord wishes to remain inviolate; and so the woman who occupies the bed of a lawful wife is a concubine. But an exception is added; for the woman, by fornication, cuts herself off, as a rotten member, from her husband, and sets him at liberty. Those who search for other reasons ought justly to be set at nought, because they choose to be wise above the heavenly teacher. They say that leprosy is a proper ground for divorce, because the contagion of the disease affects not only the husband, but likewise the children. For my own part, while I advise a religious man not to touch a woman afflicted with leprosy, I do not pronounce him to be at liberty to divorce her. If it be objected, that they who cannot live unmarried need a remedy, that they may not be burned, I answer, that what is sought in opposition to the word of God is not a remedy. I add too, that if they give themselves up to be guided by the Lord, they will never want continence, for they follow what he has prescribed. One man shall contract such a dislike of his wife, that he cannot endure to keep company with her: will polygamy cure this evil? Another man's wife shall fall into palsy or apoplexy, or be afflicted with some other incurable disease, shall the husband reject her under the pretense of incontinency? We know, on the contrary, that none of those who walk in their ways are ever left destitute of the assistance of the Spirit. For the sake of avoiding fornication, says Paul, let every man marry a wife, (1-Corinthians 7:2.) He who has done so, though he may not succeed to his wish, has done his duty; and, therefore, if any thing be wanting, he will be supported by divine aid. To go beyond this is nothing else than to tempt God. When Paul mentions another reason, namely, that when, through a dislike of godliness, wives happen to be rejected by unbelievers, a godly brother or sister is not, in such a case, liable to bondage, (1-Corinthians 7:12,15,) this is not inconsistent with Christ's meaning. For he does not there inquire into the proper grounds of divorce, but only whether a woman continues to be bound to an unbelieving husband, after that, through hatred of God, she has been wickedly rejected, and cannot be reconciled to him in any other way than by forsaking God; and therefore we need not wonder if Paul think it better that she should part with a mortal man than that she should be at variance with God. But the exception which Christ states appears to be superfluous. For, if the adulteress deserve to be punished with death, what purpose does it serve to talk of divorces? But as it was the duty of the husband to prosecute his wife for adultery, in order to purge his house from infamy, whatever might be the result, the husband, who convicts his wife of uncleanness, is here freed by Christ from the bond. It is even possible that, among a corrupt and degenerate people, this crime remained to a great extent unpunished; as, in our own day, the wicked forbearance of magistrates makes it necessary for husbands to put away unchaste wives, because adulterers are not punished. It must also be observed, that the right belongs equally and mutually to both sides, as there is a mutual and equal obligation to fidelity. For, though in other matters the husband holds the superiority, as to the marriage bed, the wife has an equal right: for he is not the lord of his body; and therefore when, by committing adultery, he has dissolved the marriage, the wife is set at liberty. And whosoever shall marry her that is divorced. This clause has been very ill explained by many commentators; for they have thought that generally, and without exception, celibacy is enjoined in all cases when a divorce has taken place; and, therefore, if a husband should put away an adulteress, both would be laid under the necessity of remaining unmarried. As if this liberty of divorce meant only not to lie with his wife; and as if Christ did not evidently grant permission in this case to do what the Jews were wont indiscriminately to do at their pleasure. It was therefore a gross error; for, though Christ condemns as an adulterer the man who shall marry a wife that has been divorced, this is undoubtedly restricted to unlawful and frivolous divorces. In like manner, Paul enjoins those who have been so dismissed to remain unmarried, or to be reconciled to their husbands, (1-Corinthians 7:11;) that is, because quarrels and differences do not dissolve a marriage. This is clearly made out from the passage in Mark, where express mention is made of the wife who has left her husband: and if the wife shall divorce her husband Not that wives were permitted to give their husbands a letter of divorcement, unless so far as the Jews had been contaminated by foreign customs; but Mark intended to show that our Lord condemned the corruption which was at that time universal, that, after voluntary divorces, they entered on both sides into new marriages; and therefore he makes no mention of adultery.

And I say unto you - Emphasis should be laid here on the word "I." This was the opinion of Jesus - this he proclaimed to be the law of his kingdom this the command of God ever afterward. Indulgence had been given by the laws of Moses; but that indulgence was to cease, and the marriage relation to be brought back to its original intention. Only one offence was to make divorce lawful. This is the law of God; and by the same law, all marriages which take place after divorce, where adultery is not the cause of divorce, are adulterous. Legislatures have no right to say that people may put away their wives for any other cause; and where they do, and where there is marriage afterward, by the law of God such marriages are adulterous!

Except it be for fornication - See on Matthew 5:32 (note). The decision of our Lord must be very unpleasant to these men: the reason why they wished to put away their wives was, that they might take others whom they liked better; but our Lord here declares that they could not be remarried while the divorced person was alive, and that those who did marry, during the life of the divorced, were adulterers; and heavy judgments were, denounced, in their law, against such: and as the question was not settled by the schools of Shammai and Hillel, so as to ground national practice on it therefore they were obliged to abide by the positive declaration of the law, as it was popularly understood, till these eminent schools had proved the word had another meaning. The grand subject of dispute between the two schools, mentioned above, was the word in Deuteronomy 24:1, When a man hath taken a wife - and she find no grace in his sight, because of some Uncleanness, ערות eruath: - this the school of Shammai held to mean whoredom or adultery; but the school of Hillel maintained that it signified any corporeal defect, which rendered the person deformed, or any bad temper which made the husband's life uncomfortable. Any of the latter a good man might bear with; but it appears that Moses permitted the offended husband to put away the wife on these accounts, merely to save her from cruel usage.
In this discourse, our Lord shows that marriage, (except in one case), is indissoluble, and should be so: -
1st, By Divine institution, Matthew 19:4.
2dly, By express commandment, Matthew 19:5.
3dly, Because the married couple become one and the same person, Matthew 19:6.
4thly, By the example of the first pair, Matthew 19:8; and
5thly, Because of the evil consequent on separation, Matthew 19:9. The importance of this subject will, I hope, vindicate or excuse, the length of these notes.

And I say unto you, Whosoever shall put away his wife, except [it be] (h) for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.
(h) Therefore in these days the laws that were made against adulterers were not regarded: for they would have no need of divorce, if the marriage had been severed by punishment of death.

And I say unto you,.... To his disciples, when they were with him alone in the house, and asked him more particularly about the subject, concerning which he had been discoursing with the Pharisees, as Mark observes, Mark 10:10 when he said to them much the same things, he had delivered before in Matthew 5:32
whosoever shall put away in his wife; separate her from his person, house and bed, and dismiss her as his wife, no more to be considered in that relation to him,
except it be for fornication; or whoredom, for defiling his bed: for this is not to be understood of fornication committed before, but of uncleanness after marriage, which destroys their being one flesh:
and shall marry another woman, committeth adultery; Marks adds, "against her"; which may be understood either of the woman he marries, which not being lawfully done, she lives in adultery with the husband of another woman; or of his former wife, and who is still his wife, and to whose injury he has married another; and he not only commits adultery himself, but, as in Matthew 5:32 "causeth her to commit adultery also", by being the occasion of marrying another man, when she is still his lawful wife:
and whoso marrieth her which is put away, for any other cause than adultery,
doth commit adultery also; since he cohabits with the wife of another man; see Gill on Matthew 5:32

And I say unto you, Whosoever shall put away his wife, except, &c.--See on Matthew 5:31.

I say unto you. We have here Christ's law of divorce in contrast with that of Moses.
Except 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.

And I say to you - I revoke that indulgence from this day, so that from henceforth, Whosoever, &c.
