1 tn Heb “like the legs which hang down from the lame” (so NASB). The is דַּלְיוּ (dalyu), from דָּלַל (dalal, “to hang; to be low; to languish”) although the spelling of the form indicates it would be from דָּלָה (dalah, “to draw” [water]). The word indicates the uselessness of the legs – they are there but cannot be used. Luther gave the verse a fanciful but memorable rendering: “Like dancing to a cripple, so is a proverb in the mouth of the fool.”
2 tn The proverb does not begin with a כְּ (bet) preposition to indicate a simile; but the analogy within the verse makes it clear that the first line is the emblem. The conjunction vav then indicates the equation – “so.”
3 sn As C. H. Toy puts it, the fool is a “proverb-monger” (Proverbs [ICC], 474); he handles an aphorism about as well as a lame man can walk. The fool does not understand, has not implemented, and cannot explain the proverb. It is useless to him even though he repeats it.
