מדרש אויף איכה 3:4

“He wore away my flesh and my skin, broke my bones” (Lamentations 3:4).
“He wore away my flesh” – this is the community. “And my skin” – this is the Sanhedrin; just as the skin protects the flesh, so the Sanhedrin protects the community. “Broke my bones [atzmotai]” – my mighty ones [itzumai], people who were like mighty warriors [benei haatzumim].
“He built against me and surrounded me with gall and hardship” (Lamentations 3:5).
“He built against me and surrounded me with gall [rosh]” – this is Nebuchadnezzar, as it is written in his regard: “You are the head [reisha] of gold” (Daniel 2:38). “And hardship” – this is Nevuzaradan. Alternatively: “Gall” – this is Vespasian; “and hardship” – this is Trajan.
“He settled me in darkness, like those long dead” (Lamentations 3:6).
“He settled me in darkness, like those long dead” – Rabbi Shmuel said: Four are considered as dead: A blind person, as it is stated: “He settled me in darkness, like those long dead.” A leper, as it is stated: “Let her not be like a corpse” (Numbers 12:12).¹⁰Aaron said this in reference to Miriam, who was afflicted with leprosy, when he asked Moses to pray on her behalf. One who does not have children, as it is written regarding Rachel: “Give me children, and if not, I am dead” (Genesis 30:1). And one who has become impoverished, as it is stated: “All the men [seeking your life] have died” (Exodus 4:19). Were they, in fact, dead? Rather, they had become impoverished.¹¹The Sages identified the men seeking Moses’s life as Datan and Aviram (see Avoda Zara 5a). They were not yet dead, as they later participated in Koraḥ’s uprising (see Numbers 16:1–2).

[3] Another interpretation: "And there will be an end..." Like Scriptures say: "For I will restore health to you, and I will heal you of your wounds" (Jeremiah 30:17). The measures of God are not like the measures of flesh and blood, for He can strike with a sword and heal with a sword. He is able to heal Israel in the very thing in which they sinned. For example, when they sinned with a cloud, it is written, "He has covered Himself with a cloud" (Lamentations 3:44), and they were struck with a cloud, as it is written, "Behold, he shall come up like clouds" (Jeremiah 4:13), and they were healed with a cloud, as it is written, "Who are these that fly as a cloud?" (Isaiah 60:8). Similarly, it is written, "And the Lord will create upon every dwelling place of mount Zion, and upon her assemblies, a cloud and smoke by day" (Isaiah 4:5). When they sinned with a thick darkness, it is written, "And darkness shall cover the earth" (Isaiah 60:2), and they were struck with darkness, as it is written, "He has made my skin black and my bones to shake" (Lamentations 3:4), and they were healed with darkness, as it is written, "Who are these that fly as a cloud?" (Isaiah 60:8). When they sinned with justice, it is written, "They judge not the cause, the cause of the fatherless" (Jeremiah 5:28), and they were struck with justice, as it is written, "He will speak judgment to the Gentiles" (Isaiah 42:1), and they were healed with justice, as it is written, "Zion shall be redeemed with judgment" (Isaiah 1:27). They were struck in dreams, "as a dream when one awakens" (Psalms 73:20), and they were healed in dreams, "Your old men shall dream dreams" (Joel 3:1). Similarly, Joseph was not sold except for the sake of dreams, as it is written, "Behold, this dreamer comes" (Genesis 37:19), and he was healed in a dream, as it is written, "And it came to pass at the end of two full years, that Pharaoh dreamed" (Genesis 41:1), "For I will restore health to you, and I will heal you of your wounds" (Jeremiah 30:17).
