Musar su Giobbe 31:21

And there are some [negative commandments] that some of the masses do not keep the main [negative commandment], such as wounding and hitting. For one that hits his fellow violates two negative commandments, as it is stated (Deuteronomy 25:3), “You shall strike him forty; you shall not add, lest you add.” And many transgress these negative commandments by hitting their wives. And our Rabbis, may their memory be blessed, said (Sanhedrin 58b), “Anyone who raises his hand to strike another, even if he does not strike him, is called wicked - as it is stated (Exodus 2:13), ‘and he said to the wicked one, “Why should you strike your friend?”’ ‘Why did you strike,’ is not stated, but rather, ‘should you strike.’” And Job said (Job 31:21), “If I raised my hand against the fatherless.” And our Rabbis, may their memory be blessed, said (Sanhedrin 58b) [that] Rav Huna would cut off the hand of the striker. He would say, “And the high arm shall be broken” (Job 38:15).

If he should occupy himself with the service of the king, let him assume as his prior duty the service of the King of Kings. Let him not exalt himself in his heart, because of royal power. Let him not hurt his fellow men with his power and that of his cohorts, as Job said (31:21), “If I have lifted up my hand against the fatherless because I saw my help in the gate.” Let him admonish the wicked and humble them, and let him intercede in favor of every man, and let him stand in the breach of those doomed to be slain, and let him rescue those who are to be taken to death, let him help the poor. Let him do all this for the sake of the Creator, blessed be He, and not in order to attain fame.
