Proverbs 15:30 New English Translation

³⁰A bright look^[a] brings joy to the heart,
and good news gives health to the body.^[b]

Proverbs 15:30 tc The LXX has “the eye that sees beautiful things.” D. W. Thomas suggests pointing מְאוֹר (m^eʾor) as a Hophal participle, “a fine sight cheers the mind” (“Textual and Philological Notes,” 205). But little is to be gained from this change.tn Heb “light of the eyes” (so KJV, NRSV). The expression may indicate the gleam in the eyes of the one who tells the good news, as the parallel clause suggests.
Proverbs 15:30 tn Heb “makes fat the bones;” NAB “invigorates the bones;” NASB “puts fat on the bones.” The word “bones” is a metonymy of subject, the bones representing the whole body. The idea of “making fat” signifies by comparison (hypocatastasis) with fat things that the body will be healthy and prosperous (e.g., Prov 17:22; 25:25; Gen 45:27-28; Isa 52:7-8). Good news makes the person feel good in body and soul.
