Commentary for Proverbs 22:8

He who sows injustice will reap violence According to his sowing will be his reaping; according to his deed will be the reception of his reward.

and the rod of his wrath will fail The rod of his ear of grain will fail more and more [interpreting עברתו as עבור, grain]. Some say: The rod of his wrath with which he rules over people will become progressively lessened because he impairs his ability.
