Rav Hamnuna said: Jerusalem was destroyed only because schoolchildren there were interrupted from studying Torah, as it is stated: “And I am filled with the wrath of God, I cannot contain it, pour it onto the infants in the street and onto the gathering of youths together, for men and women alike will be captured, the elderly along with those of advanced years” (Jeremiah 6:11). Rav Hamnuna explains: What is the reason that the wrath is poured? It is because infants are outside in the streets and are not studying Torah.
Ulla said: Jerusalem was destroyed only because people had no shame before each other, as it is stated: “They acted shamefully; they have performed abominations, yet they neither were ashamed nor did they know humiliation. Therefore, they will fall among the fallen, they will fail at the time that I punish them, said God” (Jeremiah 6:15).
Rabbi Yitzḥak said: Jerusalem was destroyed only because its small and the great citizens were equated. They did not properly value the prominent leaders of their generation, as it is stated: “And the common people were like the priest, the slave like his master, the maidservant like her mistress, the buyer like the seller, the lender like the borrower, the creditor like the one indebted to him” (Isaiah 24:2). And it is written afterward: “The land shall be utterly desolate and completely plundered, for God has said this” (Isaiah 24:3).
