Like a flying bird or a darting swallow, so is an undeserved curse. A whip for the horse, a bridle for the donkey, and a rod for the backs of fools. Like the legs of the lame that hang loose, so is a parable in the mouths of fools. Whosoever digs a pit shall fall into it, and whoever rolls a stone, it will come back on him. Whosoever goes over and rushes to interfere in a quarrel which is not their own, he is like one who grabs a dog by the ears.
