20 The tongue of the upright man is like tested silver: the heart of the evil-doer is of little value. 21 The lips of the upright man give food to men, but the foolish come to death for need of sense.

Matthew Henry's Commentary on Proverbs 10:20-21

Commentary on Proverbs 10:20-21

(Read Proverbs 10:20-21)

The tongue of the just is sincere, freed from the dross of guile and evil design. Pious discourse is spiritual food to the needy. Fools die for want of a heart, so the word is; for want of thought.
