8As is the one that bindeth a stone fast in a sling, so is he that giveth honor to a fool.
9As a thorn that is come into the hand of a drunkard, so is a parable in the mouth of fools.
10A master injureth all things when he hireth a fool or hireth mere rovers.
11As a dog returneth to his vomit, so doth a fool repeat to act in his folly.
Proverbs 26
