Proverbs 24:6-9

New International Version - UK

⁶ Surely you need guidance to wage war,
    and victory is won through many advisors.

⁷ Wisdom is too high for fools;
    in the assembly at the gate they must not open their mouths.

⁸ Whoever plots evil
    will be known as a schemer.
⁹ The schemes of folly are sin,
    and people detest a mocker.
