Midrasch zu Ejchah 3:49

“My eye will flow and will not cease, without respite. Until the Lord looks out and sees from Heaven” (Lamentations 3:49–50).
“My eye will flow and will not cease.… until the Lord looks out and sees from Heaven” – Rabbi Aḥa said in the name of Rabbi Shmuel bar Naḥman: In three places we found the Divine Presence connected with the redemption. What is the source? “A stomping ground for wild donkeys, a pasture of flocks” (Isaiah 32:14).⁷⁶This is a reference to the Temple after its destruction. What is written thereafter? “Until a spirit will be poured upon us from on high and wilderness will become fertile land and fertile land will be considered as forest” (Isaiah 32:15). Similarly, “The smallest will become a thousand, and the youngest [a mighty nation; I am the Lord, at its time, I will hasten it]” (Isaiah 60:22), and it is written thereafter: “The spirit of the Lord God is upon me, because the Lord has anointed me” (Isaiah 61:1). And this, “My eye will flow,” and it is written thereafter: “Until the Lord looks out and sees from Heaven.”
“My eye distressed my soul over all the daughters of my city” (Lamentations 3:51).
“My eye distressed my soul” – Rabban Shimon ben Gamliel said: There were five hundred primary schools in Beitar, and the smallest among them had no fewer than three hundred children. They would say: If our enemies come against us, we will emerge and stab them with these quills. When the iniquities were the cause and the enemies came, they wrapped each and every one of them in his scroll and they burned them, and I am the only one of them who survived. I applied to myself the verse: “My eye distressed my soul over all the daughters of my city.”
