Proverbs 26:12 New English Translation

¹²You have seen^[a] a man wise in his own opinion^[b]—
there is more hope for a fool^[c] than for him.

Proverbs 26:12 tn Most translations render the verse as a question (“Have you seen…?” so KJV, NASB, NIV, ESV, Holman) while sometimes this construction is turned into a conditional sentence. But the Hebrew has a perfect verb form (רָאִיתָ; raʾita), expecting past time, without an interrogative or conditional marker. See the note at Prov 26:16.
Proverbs 26:12 tn Heb “in his own eyes” (so ESV, NASB, NIV).
Proverbs 26:12 sn Previous passages in the book of Proverbs all but deny the possibility of hope for the fool. So this proverb is saying there is absolutely no hope for the self-conceited person, and there might be a slight hope for the fool—he may yet figure out that he really is a fool.
