Solomon
Proverbs 16:24ESV·traditional attribution

Gracious words are like a honeycomb, sweetness to the soul and health to the body.

Matthew Henry Presbyterian @wholebiblehenry

The pleasant words here commended must be those which the heart of the wise teaches, and adds learning to (Pro 16:23), words of seasonable advice, instruction, and comfort, words taken from God's word, for that is it which Solomon had learned from his father to account sweeter than honey and the honey-comb, Psa 19:10. These words, to those that know how to relish them, 1. Are pleasant.

John Gill Reformed Baptist @doctorgill

Pleasant words are as an honeycomb,.... Jarchi interprets it of the words of the law; but it may be much better understood of the doctrines of the Gospel; such as the doctrines of God's everlasting love, eternal election, the covenant of grace, the person of Christ as God-man; of peace and reconciliation by his blood; of remission of sins through his atoning sacrifice; of justification...

Jamieson-Fausset-Brown Reformed @jfbcommentary

(Compare Pro 15:26). Gentle, kind words, by soothing the mind, give the body health.
