욥기 29:17의 Musar

Until now we have told of the evils of cruelty, but there are places where it is necessary to conduct one's self with cruelty against the wicked, as Job said: "And I broke the jaws of the unrighteous, and plucked the prey out of his teeth" (Job 29:17), and as the Torah itself has commanded us to execute the wicked and to lash them. And thus did our rabbis say: "He who does not want to build a Sukkah, nor make fringes for his tallit… nor fix a Mezuzah on his doorpost deserves to be beaten within an inch of his life" (Ketuboth 86a). And all this requires cruelty of a sort — to pursue the wicked and to press heavily upon them in order to restore them to good conduct.
