We have here an exposition of the seventh commandment, given us by the same hand that made the law, and therefore was fittest to be the interpreter of it: it is the law against uncleanness, which fitly follows upon the former; that laid a restraint upon sinful passions, this upon sinful appetites, both which ought always to be under the government of reason and conscience, and if indulged, are equally pernicious.

I.The command is here laid down (Mat 5:27), Thou shalt not commit adultery; which includes a prohibition of all other acts of uncleanness, and the desire of them: but the Pharisees, in their expositions of this command, made it to extend no further than the act of adultery, suggesting, that if the iniquity was only regarded in the heart, and went no further, God could not hear it, would not regard it (Psa 66:18), and therefore they thought it enough to be able to say that they were no adulterers, Luk 18:11.

II.It is here explained in the strictness of it, in three things, which would seem new and strange to those who had been always governed by the tradition of the elders, and took all for oracular that they taught.

1.We are here taught, that there is such a thing as heart-adultery, adulterous thoughts and dispositions, which never proceed to the act of adultery or fornication; and perhaps the defilement which these give to the soul, that is here so clearly asserted, was not only included in the seventh commandment, but was signified and intended in many of those ceremonial pollutions under the law, for which they were to wash their clothes, and bathe their flesh in water. Whosoever looketh on a woman (not only another man's wife, as some would have it, but any woman), to lust after her, has committed adultery with her in his heart, Mat 5:28. This command forbids not only the acts of fornication and adultery, but, (1.) All appetites to them, all lusting after the forbidden object; this is the beginning of the sin, lust conceiving (Jam 1:15); it is a bad step towards the sin; and where the lust is dwelt upon and approved, and the wanton desire is rolled under the tongue as a sweet morsel, it is the commission of sin, as far as the heart can do it; there wants nothing but convenient opportunity for the sin itself. Adultera mens est - The mind is debauched. Ovid. Lust is conscience baffled or biassed: biassed, if it say nothing against the sin; baffled, if it prevail not in what is says. (2.) All approaches toward them; feeding the eye with the sight of the forbidden fruit; not only looking for that end, that I may lust; but looking till I do lust, or looking to gratify the lust, where further satisfaction cannot be obtained. The eye is both the inlet and outlet of a great deal of wickedness of this kind, witness Joseph's mistress (Gen 39:7), Samson (Jdg 16:1), David, Sa2 11:2. We read the eyes full of adultery, that cannot cease from sin, Pe2 2:14. What need have we, therefore, with holy Job, to make a covenant with our eyes, to make this bargain with them that they should have the pleasure of beholding the light of the sun and the works of God, provided they would never fasten or dwell upon any thing that might occasion impure imaginations or desires; and under this penalty, that if they did, they must smart for it in penitential tears! Job 31:1. What have we the covering of the eyes for, but to restrain corrupt glances, and to keep out of their defiling impressions? This forbids also the using of any other of our senses to stir up lust. If ensnaring looks are forbidden fruit, much more unclean discourses, and wanton dalliances, the fuel and bellows of this hellish fire. These precepts are hedges about the law of heart-purity, Mat 5:8. And if looking be lust, they who dress and deck, and expose themselves, with design to be looked at and lusted after (like Jezebel, that painted her face and tired her head, and looked out at the window) are no less guilty. Men sin, but devils tempt to sin.

2.That such looks and such dalliances are so very dangerous and destructive to the soul, that it is better to lose the eye and the hand that thus offend then to give way to the sin, and perish eternally in it. This lesson is here taught us, Mat 5:29, Mat 5:30. Corrupt nature would soon object against the prohibition of heart-adultery, that it is impossible to governed by it; "It is a hard saying, who can bear it? Flesh and blood cannot but look with pleasure upon a beautiful woman; and it is impossible to forbear lusting after and dallying with such an object." Such pretences as these will scarcely be overcome by reason, and therefore must be argued against with the terrors of the Lord, and so they are here argued against.

(1)It is a severe operation that is here prescribed for the preventing of these fleshly lusts. If thy right eye offend thee, or cause thee to offend, by wanton glances, or wanton gazings, upon forbidden objects; if thy right hand offend thee, or cause thee to offend, by wanton dalliances; and if it were indeed impossible, as is pretended, to govern the eye and the hand, and they have been so accustomed to these wicked practices, that they will not be withheld from them; if there be no other way to restrain them (which, blessed be God, through his grace, there is), it were better for us to pluck out the eye, and cut off the hand, though the right eye, and right hand, the more honourable and useful, than to indulge them in sin to the ruin of the soul. And if this must be submitted to, at the thought of which nature startles, much more must we resolve to keep under the body, and to bring it into subjection; to live a life of mortification and self-denial; to keep a constant watch over our own hearts, and to suppress the first rising of lust and corruption there; to avoid the occasions of sin, to resist the beginnings of it, and to decline the company of those who will be a snare to us, though ever so pleasing; to keep out of harm's way, and abridge ourselves in the use of lawful things, when we find them temptations to us; and to seek unto God for his grace, and depend upon that grace daily, and so to walk in the Spirit, as that we may not fulfil the lusts of the flesh; and this will be as effectual as cutting off a right hand or pulling out a right eye; and perhaps as much against the grain to flesh and blood; it is the destruction of the old man.

(2)It is a startling argument that is made use of to enforce this prescription (Mat 5:29), and it is repeated in the same words (Mat 5:30), because we are loth to hear such rough things; Isa 30:10. It is profitable for thee that one of thy members should perish, though it be an eye or a hand, which can be worse spared, and not that thy whole body should be cast into hell. Note, [1.] It is not unbecoming a minister of the gospel to preach of hell and damnation; nay, he must do it, for Christ himself did it; and we are unfaithful to our trust, if we give not warning of the wrath to come. [2.] There are some sins from which we need to be saved with fear, particularly fleshly lusts, which are such natural brute beasts as cannot be checked, but by being frightened; cannot be kept from a forbidden tree, but by cherubim, with a flaming sword. [3.] When we are tempted to think it hard to deny ourselves, and to crucify fleshly lusts, we ought to consider how much harder it will be to lie for ever in the lake that burns with fire and brimstone; those do not know or do not believe what hell is, that will rather venture their eternal ruin in those flames, than deny themselves the gratification of a base and brutish lust. [4.] In hell there will be torments for the body; the whole body will be cast into hell, and there will be torment in every part of it; so that if we have a care of our own bodies, we shall possess them in sanctification and honour, and not in the lusts of uncleanness. [5.] Even those duties that are most unpleasant to flesh and blood, are profitable for us; and our Master requires nothing from us but what he knows to be for our advantage.

3.That men's divorcing of their wives upon dislike, or for any other cause except adultery, however tolerated and practised among the Jews, was a violation of the seventh commandment, as it opened a door to adultery, Mat 5:31, Mat 5:32. Here observe,

(1)How the matter now stood with reference to divorce. It hath been said (he does not say as before, It hath been said by them of old time, because this was not a precept, as those were, though the Pharisees were willing so to understand it, Mat 19:7, but only a permission), "Whosoever shall put away his wife, let him give her a bill of divorce; let him not think to do it by word of mouth, when he is in a passion; but let him do it deliberately, by a legal instrument in writing, attested by witnesses; if he will dissolve the matrimonial bond, let him do it solemnly." Thus the law had prevented rash and hasty divorces; and perhaps at first, when writing was not so common among the Jews, that made divorces rare things; but in process of time it became very common, and this direction of how to do it, when there was just cause for it, was construed into a permission of it for any cause, Mat 19:3.

(2)How this matter was rectified and amended by our Saviour. He reduced the ordinance of marriage to its primitive institution: They two shall be one flesh, not to be easily separated, and therefore divorce is not to be allowed, except in case of adultery, which breaks the marriage covenant; but he that puts away his wife upon any other pretence, causeth her to commit adultery, and him also that shall marry her when she is thus divorced. Note, Those who lead others into temptation to sin, or leave them in it, or expose them to it, make themselves guilty of their sin, and will be accountable for it. This is one way of being partaker with adulterers Psa 50:18.

And if thy right eye offend thee,.... Or "cause thee to offend", to stumble, and fall into sin. Our Lord has no regard here to near and dear relations seeking to alienate us from God and Christ, and hinder us in the pursuit of divine things; whose solicitations are to be rejected with the utmost indignation, and they themselves to be parted with, and forsaken, rather than complied with; which is the sense some give of the words: for both in this, and the following verse, respect is had only to the law of adultery; and to such members of the body, which often are the means of leading persons on to the breach of it; particularly the eye and hand. The eye is often the instrument of ensnaring the heart this way: hence the Jews have a (z) saying,

"whoever looks upon women, at the end comes into the hands of transgression.''

Mention is only made of the right eye; not but that the left may be an occasion of sinning, as well as the right; but that being most dear and valuable, is instanced in, and ordered to be parted with:

pluck it out, and cast it from thee: which is not to be understood literally; for no man is obliged to mutilate any part of his body, to prevent sin, or on account of the commission of it; this is no where required, and if done, would be sinful, as in the case of Origen: but figuratively; and the sense is, that persons should make a covenant with their eyes, as Job did; and turn them away from beholding such objects, which may tend to excite impure thoughts and desires; deny themselves the gratification of the sense of seeing, or feeding the eyes with such sights, as are graceful to the flesh; and with indignation and contempt, reject, and avoid all opportunities and occasions of sinning; which the eye may be the instrument of, and lead unto:

for it is profitable for thee, that one of thy members should perish, and not that thy whole body should be cast into hell. This is still a continuation of the figure here used; and the meaning is, that it will turn to better account, to lose all the carnal pleasures of the eye, or all those pleasing sights, which are grateful to a carnal heart, than, by enjoying them, to expose the whole man, body and soul, to everlasting destruction, in the fire of hell.

(z) T. Bab. Nedarim, fol. 20. 1.

And if thy right eye--the readier and the dearer of the two.

offend thee--be a "trap spring," or as in the New Testament, be "an occasion of stumbling" to thee.

pluck it out and cast it from thee--implying a certain indignant promptitude, heedless of whatever cost to feeling the act may involve. Of course, it is not the eye simply of which our Lord speaks--as if execution were to be done upon the bodily organ--though there have been fanatical ascetics who have both advocated and practiced this, showing a very low apprehension of spiritual things--but the offending eye, or the eye considered as the occasion of sin; and consequently, only the sinful exercise of the organ which is meant. For as one might put out his eyes without in the least quenching the lust to which they ministered, so, "if thine eye be single, thy whole body shall be full of light," and, when directed by a holy mind, becomes an "instrument of righteousness unto God." At the same time, just as by cutting off a hand, or plucking out an eye, the power of acting and of seeing would be destroyed, our Lord certainly means that we are to strike at the root of such unholy dispositions, as well as cut off the occasions which tend to stimulate them.

for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell--He who despises the warning to cast from him, with indignant promptitude, an offending member, will find his whole body "cast," with a retributive promptitude of indignation, "into hell." Sharp language, this, from the lips of Love incarnate!
