Proverbs 26:6-12

He who sends a message by the hand of a fool Cuts off his own feet (sabotages himself) and drinks the violence [it brings on himself as a consequence]. [Prov 13:17] Like the legs which are useless to the lame, So is a proverb in the mouth of a fool [who cannot learn from its wisdom]. Like one who [absurdly] binds a stone in a sling [making it impossible to throw], So is he who [absurdly] gives honor to a fool. Like a thorn that goes [without being felt] into the hand of a drunken man, So is a proverb in the mouth of a fool [who remains unaffected by its wisdom]. Like a [careless] archer who [shoots arrows wildly and] wounds everyone, So is he who hires a fool or those who [by chance just] pass by. Like a dog that returns to his vomit Is a fool who repeats his foolishness. Do you see a man [who is unteachable and] wise in his own eyes and full of self-conceit? There is more hope for a fool than for him. [Prov 29:20; Luke 18:11; Rom 12:16; Rev 3:17]
