22Even if you beat/crush a fool severely like MET you pulverize grain with a pestle, you probably will not be able to cause him to stop ◄being foolish/doing foolish things►.
23Take good care of your flocks of sheep and herds of cattle,
22Though thou poundedest a fool in a mortar, as with a pestle smiting above dried barley (or like pounding dried barley with a pestle), his folly shall not be done away from him.
23Know thou diligently the cheer of thy beast; and behold thou thy flocks. (Diligently know the faces of thy beasts; and keep watch thou over thy flocks.)
