“The one who conceals hatred has lying lips, and whoever utters slander is a fool. When words are many, transgression is not lacking, but whoever restrains his lips is prudent. The tongue of the righteous is choice silver; the heart of the wicked is of little worth. The lips of the righteous feed many, but fools die for lack of sense.”

Proverbs 10:18–21 ESV

Our words are not just sounds. They are spiritual tools.

Solomon reminds us that the way we speak . . . how much, how often, and with what heart . . . either cultivates life or spreads decay. The wise writer walks us through the destructive potential of careless speech and the sacred influence of a guarded tongue.

What you say is a window into who you are.

Guarding Against What Festers in the Heart

“The one who conceals hatred has lying lips, and whoever utters slander is a fool.” (v. 18)

This is subtle danger. It’s not the one who explodes in anger, it’s the one who smiles while hatred simmers beneath the surface. Concealed hatred is spiritual rot. It spreads quietly. Then it spills out in slander or false accusations or twisted stories or quiet character assassination.

Solomon isn’t just warning us about gossip. He’s revealing the soul behind it.

Amy Carmichael wrote, “If I say, ‘Yes, I forgive, but I cannot forget,’ as though God, who twice a day washes all the sands on all the shores of all the world, could not wash such memories from my mind—then I know nothing of Calvary love.”

Bitterness leaks. And when it does, it often leaks from the lips.

Learning to Listen Before Speaking

“When words are many, transgression is not lacking, but whoever restrains his lips is prudent.” (v. 19)

Sometimes wisdom sounds like silence. We tend to think more words equal more influence, but Solomon says otherwise. When we rush to fill every gap with opinion or commentary, we invite sin in the process. Why? Because unguarded speech reflects an undisciplined heart.

The wise restrain their lips . . . not because they have nothing to say, but because they know not everything must be said. Their quietness is not emptiness; it’s discernment.

James echoes this: “Everyone should be quick to listen, slow to speak . . . ” (James 1:19) You can’t speak with clarity if you’ve never sat in stillness.

Feeding Others with What Flows From Christ

“The tongue of the righteous is choice silver . . . the lips of the righteous feed many . . .” (vv. 20–21)

The words of the righteous are not just moral, they’re nourishing. They feed souls. They strengthen the weary. They counsel the confused. Their value is like silver refined by truth, humility, and grace.

This is what happens when your mouth is surrendered to Christ. Your words don’t just fill time, they impart life.

In contrast, Solomon warns: “fools die for lack of sense.” Empty hearts lead to empty talk. And empty talk leads to spiritual ruin; not just for the speaker, but for those who listen.

Jesus said, “The good person out of the good treasure of his heart produces good . . . for out of the abundance of the heart his mouth speaks.” (Luke 6:45 ESV)

Open your heart before you open your mouth.

Speak not to be heard, but to build.

Let your words be few . . . but full of Christ.

Righteous lips don’t just speak truth; they feed lives.
