" A good many proverbs prove to be narrative vignettes in which ... the moral calculus of reward for the good and retribution for the wicked is turned into a seesaw of miniature narrative: “The righteous is rescued from straits, / and the wicked man comes in his stead” (11:8).... The two sequenced images, then, that the line evokes are of the good man, first seemingly pinned down and then popped out of the tight squeeze into which he has fallen, and the wicked man slipped into his place. This is very neat, but, we may ask, is that the way the world is? Obviously not—obvious, I think, not only to us but also to the poet in Proverbs, who has chosen these emblematic images to represent an underlying principle of moral causation that he believes to be present in reality but that he knows would never be so perspicuous in the untidiness of experience outside literature. This for him is precisely the advantage of literary expression, the possibility of understanding made available through “proverb and adage. "
