Midrash sur Les Lamentations 3:38

1) (Vayikra 26:16) ("I, too, will do this to you, and I shall visit terror upon you: consumption and fever, dimming the eyes and plaguing the soul; and you shall sow your seed in vain, for your foes shall eat it.") "I, too" ("af ani"): "I" shall speak only with "af" (wrath). It is "I" who built; "I" will destroy. "I" who planted; "I" will uproot. And thus is it written (Jeremiah 45:4) "What I have built, I shall destroy. What I have planted, I will uproot." "I will do this": This is more grievous to you than all, for My great name ("I" [one of the names of the L–rd]) is engraved upon you as a debtor. "to you": This came to you by your own hands, (for) evil never proceeds from Me. And thus is it written (Eichah 3:38) "From the mouth of the Most High there shall not go forth the evils, but the good."

Another interpretation: "See I, etc," (Deuteronomy 11:26). This is that which the verse stated (Lamentations 3:38), "Is it not at the word of the Most High, that weal and woe befall?" At the time that Israel stood in front of Mount Sinai, the Holy One, blessed be He, gave them the Torah. At that time, the Holy One, blessed be He, took remuneration from every [individual] that sinned. In the past the generation would pay for the sin of anyone who sinned. Our rabbis said about the generation of the Flood, "There were many among them that were proper as much as Noach, and they were erased with the generation." In the generation of [the Tower of Babel], when they sinned, the infants were charged. [But] from when Israel stood at Sinai and the Holy One, blessed be He gave them the commandments, He said, "In the past, the generations were punished for each of their [individuals]. [But] from now on, a generation will not be punished for an [individual]." Hence, "Is it not at the word of the Most High, that weal and woe befall?"

“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).

... In the hour that Shlomo built the Holy Temple, the whole world was filled with the fragrance of spices. In the end he saw that it would be destroyed and he wept, saying ‘this fragrance was all for naught!’ The Holy One said to him ‘do not be distressed, I will build it as an eternal construction “…between my breasts he shall lie.” (Shir HaShirim 1:13)’ Thus it says “His jaws are like a bed of spice…” (Shir HaShirim 5:13)
