Proverbs 24:6-8

Amplified Bible

⁶ 
For by wise guidance you can wage your war,
And in an abundance of [wise] counselors there is victory and safety.

⁷ 
Wisdom is too exalted for a [hardened, arrogant] ^[a]fool;
He does not open his mouth in the gate [where the city’s rulers sit in judgment].

⁸ 
He who plans to do evil
Will be called a schemer or deviser of evil.
