Proverbs 15:30

Two things are here pronounced pleasant: - 1. It is pleasant to have a good prospect to see the light of the sun (Ecc 11:7) and by it to see the wonderful works of God, with which this lower world is beautified and enriched. Those that want the mercy know how to value it; how would the light of the eyes rejoice their hearts! The consideration of this should make us thankful for our eyesight. 2. It is more pleasant to have a good name, a name for good things with God and good people; this is as precious ointment, Ecc 7:1. It makes the bones fat; it gives a secret pleasure, and that which is strengthening. It is also very comfortable to hear (as some understand it) a good report concerning others; a good man has no greater joy than to hear that his friends walk in the truth.

light of the eyes-- (Pro 13:9). What gives light rejoiceth the heart, by relieving from anxiety as to our course; so good report--or, "doctrine" (Isa 28:9; Isa 53:1), maketh . . . fat--or, "gives prosperity" (Pro 3:13-17; Pro 9:11). The last clause is illustrated by the first.
