Deuteronomy 32:35

35To me belongeth vengeance. This passage is quoted to different purposes by Paul, and by the author (283) of the Epistle to the Hebrews, (Romans 12:19; Hebrews 10:30;) for Paul, with a view of persuading believers to bear injuries patiently, admonishes them to “give place unto wrath,” inasmuch as God declares vengeance to be His; but the author of the Epistle to the Hebrews, proclaiming that God will be the avenger of impiety, confirms his declaration by this testimony. Hence it is that part of the commentators suppose that punishment is here denounced against heathen nations because they have cruelly afflicted God’s elect people. And, indeed, this appears to be the meaning of Paul’s words, that injuries should be patiently endured, since God claims for Himself the office of Avenger; but there is nothing to prevent the same statement from being accommodated to different uses, and therefore Paul did not irrelevantly confirm his exhortation by this saying of Moses, although it literally refers to the internal chastisements of the Church. Besides, the apostles are not in the habit of quoting every word from the testimonies which they adduce, but briefly remind their readers to examine more closely the passages quoted. But, since God here joins the two things together, that He will punish the sins of His people, and at the same time be the avenger of their oppressions, there will be nothing absurd in saying that Paul, as it were, points his finger at this passage; (284) still, the simple explanation will be, that the general declaration is accommodated to a special case, in order that believers should bear their injuries patiently, and leave to God the office which He pronounces to appertain to Himself. In my judgment, indeed, these words are connected with the preceding verse; for God pertinently confirms His statement, that he takes account of the number of men’s sins, and has them stored among His treasures, by adding that the power and office of judging rests with Himself; inasmuch as these two things are contrary to each other, that He should be cognizant of whatever is done unrighteously and amiss, and still leave it unpunished. Not that it is opposed to God’s justice to pardon sinners when they repent, but because this principle always continues firm, that God is the judge of the world, for the punishment of all iniquities. Thus the confidence of hypocrites is destroyed, who flatter themselves with the hope of impunity, unless they are overtaken by immediate punishment.

The clause which follows some interpreters pervert by supplying the relative, “in the time in which their foot shall slide;” whereas Moses simply concludes that they will fall in their due time, or that, although they may think they stand, their ruin or fall was not far off; and this is further confirmed by what he adds, viz., that their day of calamity was at hand. This statement, as I have before said, often occurs in the Prophets, that there is with God a fit time, (285) in which to punish the sins which He has appeared to overlook, and therefore His long-suffering detracts nothing from the judgment which He delays. In this doctrine there is a twofold moral; first, that those whom God spares for a time, should not give way to self-indulgence; and, secondly, that the prosperity of the wicked should not disturb the minds of believers, but that they should allow God to decide the time and the place of executing vengeance. Inasmuch, however, as God’s delay renders hypocrites secure, so that they lull themselves to sleep in their vices, and, although they hear that they will have to render account of them, thoughtlessly indulge themselves during (286) their period of enjoyment, Moses declares that the day is near, and makes haste; for, if God does not openly alarm them, and reduce them to straits, they exult in their immunity. Hence those blasphemous sayings recorded by Isaiah, (Isaiah 5:19,) “Let him make speed, and hasten his work that we may see it; and let the counsel of the Holy One draw nigh and come, that we may know it! “Meanwhile we must bear in mind the words of Habakkuk, (Habakkuk 2:3,) “Though the prophecy tarry, wait for it; because it will surely come, it will not tarry.”
