Мидраш к Эйха 3:37

“Who is it who said and it occurred, if the Lord did not command it?” (Lamentations 3:37).
“Who is it who said and it occurred, if the Lord did not command it?” – who did command? Haman commanded, but the Holy One blessed be He did not command. Haman commanded “to destroy, to kill, and to eliminate” (Esther 3:13). But the Holy One blessed be He did not command it, but rather, “the plot [that he devised]…return [upon his head]” (Esther 9:25).
“Is it not from the mouth of the Most High that evil and good emerge?” (Lamentations 3:38).
“Is it not from the mouth of the Most High that evil and good emerge?” – Rabbi Elazar said: From the moment that the Holy One blessed be He said: “See, I have placed before you today: life and good, and death and evil” (Deuteronomy 30:15), no good has emerged for a performer of evil nor evil for a performer of good, but rather good for a performer of good and evil for a performer of evil, just as it says: “The Lord will reward the performer of evil in accordance with his wickedness” (II Samuel 3:39).
“Of what shall a living man complain, each man for his sins?” (Lamentations 3:39).
“Of what shall a living man complain?” – it is sufficient for him that he is alive. Rabbi Levi said: The Holy One blessed be He said: Your life is in My hands, yet you complain? Rabbi Huna said: Let him stand like a mighty one, confess his sins, and not complain. Rabbi Berekhya said: Of what shall he complain about the One who gives life to the worlds? If he seeks to complain, it should be each man for his sins. Rabbi [Yehuda HaNasi] says: Descendants of bearers of grievance; Adam, the first man, after all the good that I bestowed upon him, he expresses a grievance before Me and says: “The woman whom You gave to be with me, [she gave me from the tree, and I ate]” (Genesis 3:12). Jacob, too, did so. I am engaged in crowning his son king in Egypt, and he expresses a grievance before Me: “[Why do you say, Jacob…] my way is hidden from the Lord” (Isaiah 40:27). His children, too, I am engaged in providing them with easily digestible bread so that no one among them will be afflicted with indigestion or diarrhea, and they express a grievance before Me: “Our soul loathes this insubstantial bread” (Numbers 21:5). Zion, too, is similar: “Zion said: The Lord has forsaken Me and the Lord has forgotten Me” (Isaiah 49:14).

And Pharaoh charged all his people, saying: “Every son that is born ye shall cast into the river” (Exod. 1:22). Thereupon, the Holy Spirit exclaimed: Who is he that saith, and it cometh to pass, when the Lord commandeth it not? (Lam. 3:37). Pharaoh decreed that the firstborn children should be cast into the river, but the Holy One, blessed be He, did not ordain that. On the contrary, The more they afflicted them, the more they multiplied, and the more they spread abroad (Exod. 1:12).

Haman wanted to destroy all the Jews, but the Holy One, blessed be He, did not desire it, and therefore: Whereas it was turned to the contrary, that the Jews ruled over them that hated them (Est. 9:1). Balaam and Balak wanted to curse Israel, but the Holy One, blessed be He, did not agree, as it is said: Nevertheless, the Lord thy God will not hearken unto Balaam (Deut. 23:6). Hence it is said: Who is he that saith, and it came to pass, when the Lord commandeth it not? (Lam. 3:37). Hadrian said to R. Joshua: “Mighty is the lamb that can survive among seventy wolves.” And he replied: “Mighty is the shepherd who can save and protect the lamb, and destroy the wolves surrounding her.” Therefore, it is written: No weapon that is formed against thee shall prosper (Ps. 54:17).
