Proverbs 10:21

Feed - The Hebrew word, like ποιμαίνειν poimainein, includes the idea of guiding as well as nourishing; doing a shepherd’s work in both.

For want of wisdom - Some prefer, through him who wanteth understanding, referring to a person. The wise guides others to safety; the fool, empty-headed, and empty-hearted, involves others like himself in destruction.
