What is the meaning of Proverbs 10:21?

Setting the scene

“The lips of the righteous feed many, but fools die for lack of judgment” (Proverbs 10:21). Nestled in a chapter of sharp contrasts, this proverb sets life-giving words against deadly foolishness. It invites us to watch our speech, value sound judgment, and realize that every sentence we utter carries either nourishment or poison (Proverbs 18:21).


The lips of the righteous

• A righteous person’s mouth is connected to a heart aligned with God (Luke 6:45).

• Earlier in the chapter we read, “The mouth of the righteous is a fountain of life” (Proverbs 10:11).

• When God rules the heart, speech naturally blesses others, echoing Paul’s call: “Let no unwholesome talk come out of your mouths, but only what is helpful for building up” (Ephesians 4:29).

• Righteous lips also speak truth, mirroring the King’s delight in “righteous lips” (Proverbs 16:13).


Feed many

• “Feed” pictures nourishing souls much like bread sustains bodies—“Man shall not live on bread alone, but on every word that comes from the mouth of God” (Matthew 4:4).

• Spiritual feeding happens through:

– Encouragement (Proverbs 12:25).

– Correction done in love (Proverbs 27:6).

– Teaching the Scriptures so “the word of Christ may dwell in you richly” (Colossians 3:16).

• Jesus told Peter, “Feed My lambs” (John 21:15). Righteous lips join that same mission.


But fools die

• The proverb pivots abruptly: where wise speech gives life, foolishness courts death.

• “A fool’s mouth is his ruin, and his lips are a snare to his soul” (Proverbs 18:7).

• Spiritual death is the endpoint of unrepentant folly, reflecting Hosea 4:6, “My people are destroyed for lack of knowledge.”


For lack of judgment

• Judgment here refers to discernment—the ability to choose God’s way (Proverbs 1:7).

• Fools ignore counsel (Proverbs 12:15) and resist correction (Proverbs 15:32).

• Without sound judgment they wander into moral and eternal disaster, fulfilling the warning, “There is a way that seems right to a man, but its end is the way of death” (Proverbs 14:12).


Putting it into practice

• Store up Scripture so your mouth overflows with life (Psalm 119:11).

• Weigh every word: Will it edify or erode? (Colossians 4:6).

• Seek godly counsel to sharpen discernment (Proverbs 13:20).

• Aim for speech that reflects Christ’s grace and truth, becoming a conduit of daily bread to “many.”


summary

Proverbs 10:21 delivers a clear choice. Righteous lips, saturated with God’s Word, become spiritual bread for a hungry world. Foolish lips, empty of discernment, lead their owners to ruin. Choose the path of wisdom: fill your heart with truth, let your speech nourish others, and watch God use your words to spread life.
