Proverbs 15:30 - Joseph Benson’s Commentary on the Old and New Testaments

The light of the eyes rejoiceth the heart, &c. “In the same manner that the sensible light rejoices a sound eye, and diffuses its pleasure through the whole soul, so a good reputation gives pleasure, and contributes to the health of the body. The wise man frequently advises his disciple to labour for a good reputation: see Proverbs 10:7; Proverbs 22:1. He often proposes to him human motives, and reasons of private interest, to incline him to virtue and his own good: weak minds have need of this sort of succours. They raise them, by little and little, to more elevated sentiments, and to the most pure and sacred motives.” See Calmet.
