Commentary
4 notes on this verseA wise man not satisfied with his wisdom, but still seeking the increase of it; the more he has the more he would have: The heart of him that has understanding, rejoices so in the knowledge it has attained to that it is still coveting more, and in the use of the means of knowledge is still labouring for more, growing in grace, and in the knowledge of Christ.
This site's exposition
A joyful heart makes a cheerful countenance
on Proverbs 15:13-15
“A joyful heart makes a cheerful countenance,” while “sorrow of the heart crushes the spirit”. “A discerning heart seeks knowledge,” while “the mouth of a fool feeds on folly”. “All the days of the oppressed are bad,” yet “a cheerful heart has a continual feast,” the heart outweighing the circumstances.
This site's exposition
A discerning heart seeks knowledge
Both lines speak of appetite, the heart hunting for knowledge and the mouth grazing on folly. Matthew Henry reads the discerning heart as never satisfied with its wisdom, wanting more the more it has. The fool is content with his fodder.
