Proverbs 15:2

Behold, they pour forth speech with their mouth; Swords are in their lips, For, they say, “Who hears?”

A prudent man conceals knowledge, But the heart of fools proclaims folly.

The heart of the righteous ponders how to answer, But the mouth of the wicked pours forth evil things.

For the dream comes through abundant endeavor and the voice of a fool through abundant words.

Yet the simpleminded fool multiplies words. No man knows what will happen, and who can tell him what will come after him?
