² tn Or “more willing to learn.” L&N 27.48 and BDAG 404 s.v. εὐγενής 2 both use the term “open-minded” here. The point is that they were more receptive to Paul’s message.

² sn Different people learn differently. There are three types of people in this proverb: the scorner with a closed mind, the simpleton with an empty mind, and the discerning person with an open mind (D. Kidner, Proverbs [TOTC], 135). The simpleton learns by observing a scoffer being punished, even though the punishment will have no effect on the scoffer.

³ tn Heb “the naive” or “simpleton.” The substantival adjective פֶּתִי (peti) means “simple; open-minded” in the sense of being open and easily influenced by either wisdom or folly (BDB 834 s.v.; HALOT 989 s.v. I פֶּתִי). The simpleton is easily enticed and misled (Prov 1:32; 7:7; 9:6; 22:3; 27:12); believes everything, including bad counsel (Prov 14:15); lacks moral prudence (Prov 8:5; 19:25); needs discernment (Prov 21:11); but is capable of learning (Prov 9:4, 16). The related verb means “to be wide open; open-minded; enticed, deceived” (BDB 834). The term describes one easily persuaded and gullible, open to any influence, good or bad (cf. NLT “the simpleminded”). This is the “wide-eyed youth” who is headed for trouble unless he listens to the counsel of wisdom.
