Proverbs 10:13

11 The mouth of the righteous is a fountain of life, but the mouth of the wicked conceals violence.

12 Hatred stirs up dissension, but love covers all transgressions.

Wisdom is found on the lips of the discerning, but a rod is for the back of him who lacks judgment.

14 The wise store up knowledge, but the mouth of the fool invites destruction.

15 The wealth of the rich man is his fortified city, but poverty is the ruin of the poor.

Do read the surrounding verses too, because the context often says more than a single verse.
