Proverbs 10:18

Proverbs 10:18, in plain English

When someone pretends to feel one way while hiding hatred, they're lying with everything about themselves, and spreading false stories about others is foolish and destructive.

Why it's here

Solomon is exposing two kinds of dishonesty: the internal lie of concealing hatred while appearing friendly, and the external lie of slander. Both reveal a foolish character that destroys trust and community. He's warning about the damage of false representation.

Who's speaking

Solomon, identifying deep character issues that lead to foolishness.

Where it sits in the story

This connects to Jesus's teaching about the Pharisees whitewashing tombs—appearing righteous outwardly while harboring corruption within. It points to the importance of integrity between inner and outer, between what we feel and what we claim.

The scholarly reading

The person who harbors hatred while maintaining a false exterior is a chronic liar, while the one who spreads slander about others demonstrates fundamental foolishness.

Language and setting

The construction sōnēʾ mekasseh śfātayim—literally 'one who hates covers lips'—portrays someone who conceals enmity behind false civility. Such concealment constitutes active falsehood (yidbar šāqār, 'speaks lies'). The second clause, 'whoever spreads slander' (v'nōgēd dibbāh), represents the inverse problem: internal hatred becomes external weaponization through gossip. Both constitute folly (kesîl), though one operates through concealment and the other through exposure. The proverb addresses the varieties of malice and their expressions.

Voice

Solomon, who navigated court environments where hidden enmities and public slanders both threatened stability.

Significance

This verse illustrates Scripture's concern with the alignment of internal and external—the 'hidden things' will be revealed (1 Corinthians 4:5). It anticipates Jesus's teaching that the mouth speaks what fills the heart (Matthew 12:34).

16The labor of the righteous leads to life, but the gain of the wicked brings punishment.

17Whoever heeds instruction is on the path to life, but he who ignores reproof goes astray.

18The one who conceals hatred has lying lips, and whoever spreads slander is a fool.

19When words are many, sin is unavoidable, but he who restrains his lips is wise.

20The tongue of the righteous is choice silver, but the heart of the wicked has little worth.
