[18:1] 1 tn The Niphal participle functions substantively and has a reflexive nuance: “one who has separated himself” (cf. KJV, ASV, NASB). He is not merely anti-social; he is a problem for society since he will defy sound judgment. The Mishnah uses the verse to teach the necessity of being part of a community because people have social responsibilities and need each other (m. Avot 2:4).
[18:1] 2 tc The MT has “seeks [his own] desire[s].” The translation in the LXX represents a Hebrew Vorlage of לְתֹאֲנָה (lÿto’anah) instead of לְתַאֲוָה (lÿta’avah); this could be translated “seeks his own occasion,” that is, “his own pretext” (C. H. Toy, Proverbs [ICC], 354; cf. NAB). The MT makes sense as it stands and the emendation is not really necessary.
[18:1] 3 tn Heb “breaks out”; NRSV “showing contempt for”; NLT “snarling at.” This individual breaks out in contention against sound judgment. He is in opposition to society (e.g., Prov 17:14; 20:3).
[18:2] 4 sn This expression forms an understatement (tapeinosis); the opposite is the point – he detests understanding or discernment.
[18:2] 5 tn The Hitpael infinitive construct בְּהִתְגַּלּוֹת (bÿhitgalot) functions nominally as the object of the preposition. The term means “reveal, uncover, betray.” So the fool takes pleasure “in uncovering” his heart.
[18:2] 6 tn Heb “his heart.” This is a metonymy meaning “what is on his mind” (cf. NAB “displaying what he thinks”; NRSV “expressing personal opinion”). This kind of person is in love with his own ideas and enjoys spewing them out (W. McKane, Proverbs [OTL], 515). It is the kind of person who would ask a question, not to learn, but to show everyone how clever he is (cf. TEV).
