20 The tongue of the upright man is like tested silver: the heart of the evil-doer is of little value.

Matthew Henry's Commentary on Proverbs 10:20

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.
