Proverbs 26:9

Like the legs of the lame that hang loose: so is a parable in the mouth of fools.

As one who binds a stone in a sling, so is he who gives honor to a fool.

As an archer who wounds all, so is he who hires a fool or he who hires those who pass by.

As a dog that returns to his vomit, so is a fool who repeats his folly.
