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.

Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding.

Forsake the foolish, and live.

He that is hasty of spirit exalteth folly.

In his disease he sought not to the Lord, but to the physicians.

It is an honour for a man to cease from strife: but every fool will be meddling.

The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.

The foolishness of fools is folly.

Though thou shouldest bray a fool in a mortar among wheat with a pestle, yet will not his foolishness depart from him.
