Deuteronomy 31:17

17.Then my anger shall be kindled against them. By this denunciation of punishment, God undoubtedly desired to put a restraint upon the senselessness of the people; but since this was done without their profiting by it, there was another advantage in this lesson, viz., that, after having been seriously chastised according to their deserts, they should at length repent though it might be late. Otherwise these punishments would have been inflicted in vain; and it would have never suggested itself to their minds that they received the just recompense of their ingratitude and perfidiousness. This is indeed the first step of prudence, voluntarily to choose that which is right; but the second is to beware, when we have listened to admonition, and to make a stand against evil. But, if our minds are so blinded, that reproofs and threats profit us nothing, there is still a third, i.e., that those who have been careless in prosperity should at length begin to perceive that they are smitten by God’s hand, and thus be driven to acknowledge their guilt. Although, therefore, the simple admonition, as long as it was not followed by its consequences, was despised by the Israelites; still, when they were further instructed by its result, and by experience, it produced its fruit; and the same is daily the case with ourselves. There is scarcely one in ten of the godly, who, as long as God postpones His punishments, anticipates His judgment, but those who are aroused from their torpor, seriously consider the threats which they had hitherto passed over with indifference, and, being brought under conviction, condemn themselves.

By the word אפי, ephi, I here rather understand His face than His wrath; (243) for the expression is more appropriate; and then he sets forth the effect of His wrath, viz., that, being deprived of His aid, they shall be overtaken by all sorts of evils, until they are consumed and perish. Moreover, He affirms that they should be brought into such straits as should extort from them the confession, that the miseries which they suffered were tokens of God’s alienation from them. But He adds, that He would not then listen to their prayers. Hence are we taught that, as our happiness depends on God’s paternal favor, so there is nothing worse for us than to be forsaken by Him, as if He regarded us with no further care; and the lesson we are to learn is, that there is nothing more desirable for us than that He should honor us with His countenance. We read respecting all His creatures, in Psalms 104:29, that they are troubled when He hides His face; but here it is more clearly perceived that nothing can be imagined more miserable than we are, when “our iniquities have separated between us and our God, and our sins have hid his face from us, that he will not hear,” as Isaiah says, (Isaiah 59:2.)

I have already stated, that the greatness of their miseries is expressed, when the people shall confess that they are thus grievously afflicted, because God is departed from them; for it was by no light punishments that they would be brought to this state of feeling, especially considering their great hardness of heart and blind obstinacy. It follows then, that severe punishments are indicated, that should compel them, though unwillingly, to reflect on God’s anger, which they had previously taken no account of. Still, this confession is not referred to as the fruit or sign of sincere repentance; for, if the sinner sincerely flies to God, God will be sure to meet him, since he is inclined to mercy. But in this place He declares that He will not be favorable to them, but will suffer them to pine away in their wretchedness, for God says of Himself that He will “hide His face from them,” in the 18th verse, with a deeper meaning than just before, in that He will take no notice of their groans and lamentations, and by the very continuance of their punishments will show how greatly wroth with them He is.
