Proverbs 12:8 New English Translation

⁸A person^[a] will be praised in accordance with^[b] his wisdom,
but the one with a bewildered mind^[c] will be despised.

Proverbs 12:8 tn Heb “a man.”
Proverbs 12:8 tn Heb “to the mouth of.” This idiom means “according to” (BDB 805 s.v. פֶּה 6.b.(b); cf. KJV, NAB, NIV). The point is that praise is proportionate to wisdom.
Proverbs 12:8 tn Heb “bent of mind.” The verb עָוָּה (ʿavah) occurs four times in the Niphal. In Isa 21:3 and Ps 38:6 it describes someone who is dazed or bewildered; in 1 Sam 20:30 it is derogatory, probably meaning moral perversity. Here it contrasts wisdom, so “bewildered” is likely, but it may also mean “perverse” (NASB, NRSV, NKJV), “warped” (NIV, NLT), “twisted” (ESV). The noun לֵב (lev, “mind, heart”) is a genitive of specification. It functions as a metonymy of association for “mind; thoughts” (BDB 524 s.v. 3) and “will; volition” (BDB 524 s.v. 4). This person does not perceive things as they are, and so makes wrong choices. His thinking is all wrong.
