The fifth and last pentad (vv. 17, 18) fitly closes the series, by its five precepts, of which, three, reaching behind all such outward acts as are required or forbidden in the foregoing, deal with the state of the heart toward our neighbour which the law of holiness requires, as the soul and the root of all righteousness. It closes with the familiar words, so simple that all can understand them, so comprehensive that in obedience to them is comprehended all morality and righteousness toward man: "Thou shalt love thy neighbour as thyself." The verses read, "Thou shalt not hate thy brother in thine heart: thou shalt surely rebuke thy neighbour, and not bear sin because of him. Thou shalt not take vengeance, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the Lord!" Most instructive it is to find it suggested by this order, as the best evidence of the absence of hate, and the truest expression of love to our neighbour, that when we see him doing wrong we shall rebuke him. The Apostle Paul has enjoined upon Christians the same duty, indicating also the spirit in which it is to be performed (Gal. vi. 1): "Brethren, even if a man be overtaken in any trespass, ye which are spiritual, restore such a one in a spirit of meekness; looking to thyself, lest thou also be tempted." Thus, if we will be holy, it is not to be a matter of no concern to us that our neighbour does wrong, even though that wrong do not directly affect our personal well-being. Instead of this, we are to remember that if we rebuke him not, we ourselves "bear sin, because of him;" that is, we ourselves, in a degree, become guilty with him, because of that wrong-doing of his which we sought not in any way to hinder. But although, on the one hand, I am to rebuke the wrong-doer, even when his wrong does not touch me personally, yet, the law adds, I am not to take into my own hands the avenging of wrongs, even when myself injured; neither am I to be envious and grudge any neighbour the good he may have; no, not though he be an ill-doer and deserve it not; but be he friend or foe, well-doer or ill-doer, I must love him as myself. What an admirable epitome of the whole law of righteousness! a Mosaic anticipation of the very spirit of the Sermon on the Mount. Evidently, the same mind speaks in both alike; the law the same, the object and aim of the law the same, both in Leviticus and in the Gospel. In this law we hear: "Ye shall be holy: for I the Lord your God am holy;" in the Sermon on the Mount: "Ye shall be perfect, as your heavenly Father is perfect."
