Mishle 26:5-7

Orthodox Jewish Bible

⁵ Answer a kesil (fool) according to his folly, lest he be chacham in his own eyes.

⁶ He that sendeth a message by the yad of a kesil (fool) cutteth off the raglayim, and drinketh chamas.

⁷ The legs of the pisei’ach (lame man) hang limp; so is a mashal in the peh (mouth) of kesilim.
