Proverbs 16:10 New English Translation

¹⁰The divine verdict^[a] is in the words^[b] of the king,
his pronouncements^[c] must not act treacherously^[d] against justice.

Proverbs 16:10 tn Heb “oracle” (so NAB, NIV) or “decision”; TEV “the king speaks with divine authority.” The term קֶסֶם (qesem) is used in the sense of “oracle; decision; verdict” (HALOT 1115-16 s.v.). The pronouncements of a king form an oracular sentence, as if he speaks for God; they are divine decisions (e.g., Num 22:7; 23:23; 2 Sam 14:20).
Proverbs 16:10 tn Heb “on the lips.” The term “lips” is a metonymy of cause referring to what the king says—no doubt what he says officially.
Proverbs 16:10 tn Heb “his mouth.” The term “mouth” is a metonymy of cause for what the king says: his pronouncements and legal decisions.
Proverbs 16:10 sn The second line gives the effect of the first: If the king delivers such oracular sayings (קֶסֶם, qesem, translated “divine verdict”), then he must be careful in the decisions he makes. The imperfect tense then requires a modal nuance to stress the obligation of the king not to act treacherously against justice. It would also be possible to translate the verb as a jussive: Let the king not act treacherously against justice. For duties of the king, see Ps 72 and Isa 11. For a comparison with Ezek 21:23-26, see E. W. Davies, “The Meaning of qesem in Prov 16:10, ” Bib 61 (1980): 554-56.
