Proverbs 26:4-8

Answer not a fool according to his folly, lest thou also be like unto him.

Answer a fool according to his folly, lest he be wise in his own conceit.

He that sendeth a message by the hand of a fool cutteth off the feet, and drinketh damage.

The legs of the lame are not equal: so is a parable in the mouth of fools.

As he that bindeth a stone in a sling, so is he that giveth honour to a fool.
