מדרש על איוב 36:10

See I, etc. (Deuteronomy 11:26): This is what is stated in the verse (Job 36:10-12), "He opens their ear by discipline, etc. If they will listen and serve, they shall spend their days in goodness, their years in delight. But if they will not listen, they shall perish by the sword." "He opens their ear by discipline" - the Holy One, blessed be He, does not bring distress to a person until he opens his ear and warns him, so that he can repent. If he repents, behold, that is good. If not, He brings bad things upon him. From who do you learn [this]? From Pharaoh, king of Egypt. When [God] wanted to bring a plague upon him, he would send and warn him about it through His servant Moshe, as stated (Exodus 10:4), "Tomorrow I will bring locusts on your territory." And so [too], "I will plague your whole country with frogs" (Exodus 7:27). He warns about it "by discipline," [meaning] by the discipline of the Torah. "And he orders them back from wickedness" (Job 36:10), from the cheating people and from cheating to the Holy One, blessed be He. "They shall spend their days in goodness," (Job 36:11) [meaning,] they will complete their years in goodness.
