In close connection with the foregoing, the next precept forbids, not precisely "tale-bearing," but "slander," as the word is elsewhere rendered, even in the Revised Version. In the court of judgment, slander is not to be uttered nor listened to. The clause which follows is obscure; but means either, "Thou shalt not, by such slanderous testimony, seek in the court of judgment thy neighbour's life," which best suits the parallelism; or, perhaps, as the Talmud and most modern Jewish versions interpret, "Thou shalt not stand silent by, when thy neighbour's life is in danger in the court of judgment, and thy testimony might save him." And then again comes in the customary refrain, reminding the Israelite that in every court, noting every act of judgment, and listening to every witness, is a Judge unseen, omniscient, absolutely righteous, under whose final review, for confirmation or reversal, shall come all earthly decisions: "I," who thus speak, "am the Lord!"
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."
The third division of this chapter (vv. 19-32) opens with a general charge to obedience: "Ye shall keep My statutes;" very possibly, because several of the commands which immediately follow might seem in themselves of little consequence, and so be lightly disobeyed. The law of ver. 19 prohibits raising hybrid animals, as, for example, mules; the next command apparently refers to the chance, through sowing a field with mingled seed, of giving rise to hybrid forms in the vegetable kingdom. The last command in this verse is obscure both in meaning and intention. It reads (R.V.), "Neither shall there come upon thee a garment of two kinds of stuff mingled together." Most probably the reference is to different materials, interwoven in the yarn of which the dress was made; but a difficulty still remains in the fact that such admixture was ordered in the garments of the priests. Perhaps the best explanation is that of Josephus, that the law here was only intended for the laity; which, as no question of intrinsic morality was involved, might easily have been. But when we inquire as to the reason of these prohibitions, and especially of this last one, it must be confessed that it is hard for us now to speak with confidence. Most probable it appears that they were intended for an educational purpose, to cultivate in the mind of the people the sentiment of reverence for the order established in nature by God. For what the world calls the order of nature is really an order appointed by God, as the infinitely wise and perfect One; hence, as nature is thus a manifestation of God, the Hebrew was forbidden to seek to bring about that which is not according to nature, unnatural commixtures; and from this point of view, the last of the three precepts appears to be a symbolic reminder of the same duty, namely, reverence for the order of nature, as being an order determined by God.
