I. An evil proverb commonly used by the Jews in their captivity. We had one before (ch. xii. 22) and a reply to it; here we have another. That sets God's justice at defiance: "The days are prolonged and every vision fails; the threatenings are a jest." This charges him with injustice, as if the judgments executed were a wrong: "You use this proverb concerning the land of Israel, now that it is laid waste by the judgments of God, saying, The fathers have eaten sour grapes and the children's teeth are set on edge; we are punished for the sins of our ancestors, which is as great an absurdity in the divine regimen as if the children should have their teeth set on edge, or stupefied, by the fathers' eating sour grapes, whereas, in the order of natural causes, if men eat or drink any thing amiss, they only themselves shall suffer by it." Now, 1. It must be owned that there was some occasion given for this proverb. God had often said that he would visit the iniquity of the fathers upon the children, especially the sin of idolatry, intending thereby to express the evil of sin, of that sin, his detestation of it, and just indignation against it, and the heavy punishments he would bring upon idolaters, that parents might be restrained from sin by their affection to their children and that children might not be drawn to sin by their reverence for their parents. He had likewise often declared by his prophets that in bringing the present ruin upon Judah and Jerusalem he had an eye to the sins of Manasseh and other preceding kings; for, looking upon the nation as a body politic, and punishing them with national judgments for national sins, and admitting the maxim in our law that a corporation never dies, reckoning with them now for the iniquities of former ages was but like making a man, when he is old, to possess the iniquities of his youth, Job xiii. 26. And there is no unrighteousness with God in doing so. But, 2. They intended it as a reflection upon God, and an impeachment of his equity in his proceedings against them. Thus far that is right which is implied in this proverbial saying, That those who are guilty of wilful sin eat sour grapes; they do that which they will feel from, sooner or later. The grapes may look well enough in the temptation, but they will be bitter as bitterness itself in the reflection. They will set the sinner's teeth on edge. When conscience is awake, and sets the sin in order before them, it will spoil the relish of their comforts as when the teeth are set on edge. But they suggest it as unreasonable that the children should smart for the fathers' folly and feel the pain of that which they never tasted the pleasure of, and that God was unrighteous in thus taking vengeance and could not justify it. See how wicked the reflection is, how daring the impudence; yet see how witty it is, and how sly the comparison. Many that are impious in their jeers are ingenious in their jests; and thus the malice of hell against God and religion is insinuated and propagated. It is here put into a proverb, and that proverb used, commonly used; they had it up ever and anon. And, though it had plainly a blasphemous meaning, yet they sheltered themselves under the similitude from the imputation of downright blasphemy. Now by this it appears that they were unhumbled under the rod, for, instead of condemning themselves and justifying God, they condemned him and justified themselves; but woe to him that thus strives with his Maker.
