4Do not answer a fool according to his folly, lest thou also become equal unto him.
5Answer a fool according to his folly, lest he be wise in his own eyes.
6He choppeth off the feet, and drinketh vexation, that sendeth important messages by the hand of a fool.
7Too feebly hang down the thighs on a lame man: so is a parable in the mouth of fools.
