... The angels said before the Holy One, ‘Master of the World! Isn’t this Jerusalem?!’ as it is said “This is Jerusalem; in the midst of the nations I have placed her…” (Yechezkel 5:5) He replied to them, “But she exchanged My judgments for wickedness more than the nations…” (Yechezkel 5:6) They said to Him, “But they are Your people and Your inheritance, which You brought out with Your great strength…” (Devarim 9:29) He replied to them, “For My people have forgotten Me; they burn incense to vanity…” (Yirmiyahu 18:15) They said to Him, ‘act for the sake of the forefathers!’ He replied to them, “…the fathers are kindling fire…” (Yirmiyahu 7:18) They said to Him, ‘act for the sake of the children!’ He replied to them, “But they rebelled against Me and would not consent to hearken to Me…” (Yechezkel 20:8) They said to Him, ‘act for the sake of the tribe of Yehudah!’ “And Judah did what displeased the Lord…” (Melachim I 14:22) They said to Him, ‘act for the sake of the leaders!’ He replied to them, “Its heads judge for bribes…” (Micha 3:11) They said to Him, ‘act for the sake of the tribes!’ He replied to them, ‘and Gad, and Reuven and the half tribe of Menashe…’ They said to Him, ‘act for the sake of the tribe of Dan!’ He replied to them, “And the children of Dan set up for themselves the graven image.” (Shoftim 18:30) They said to Him,’ act for the sake of the students!’ He replied to them, “…And those who hold onto the Torah did not know Me…” (Yirmiyahu 2:8) They said to Him, ‘act for the sake of the prophets!’ He replied to them, “[It was] for the sins of her prophets, the iniquities of her priests…” (Eicha 4:13) They said to Him, ‘act for the sake of the kings!’ He replied to them, “And the altars that were on the roof, [the roof of] Ahaz's upper chamber, which the kings of Judah had made…” (Melachim II 23:12) The ministering angels said to Him, ‘act for our sake!’ He replied to them, “But they mocked the messengers of God…” (Divre HaYamim II 36:16) They said to Him, ‘act for the sake of Your name which is called upon them!’ He replied to them, ‘they have profaned My holy name.’ They said to Him, ‘You do not want to be appeased, what is the image of their father doing by You?’ “He has cast down from heaven to earth the glory of Israel…” (Eicha 2:1) This statement with which they clothed You, what has it done to You?! If the thing were not written, it would be impossible to say “The Lord has done what He devised, He has carried out His word…” (Eicha 2:17) They said to Him, ‘Master of the World! Is this not Jerusalem about whom you wrote “Behold on [My] hands have I engraved you…”’ (Yeshayahu 49:16) He replied to them, “I, too, shall clap My hands, one upon the other, and I shall put My fury to rest…” (Yechezkel 21:22) Since Zion saw that He did not want to be appeased, she started up and said “The Lord has forsaken me, and the Lord has forgotten me." (Yeshayahu 49:14) May it be Your will Lord our God and God of our fathers that Your Temple be rebuilt speedily in our days, that your Presence return within it, that You gather my exiles from the four corners of the world, that they rebuild the cities of Yehudah and settle Shechem and inherit it speedily. Amen.

... Teach us oh, teacher: once the Ninth of Av has ended, is everything permitted? R’ Chiyah the Great taught like this: once the Ninth of Av has ended, one is permitted to do anything. Why? Because it is like the case of a person whose dead is laid out before him, who is forbidden to eat meat or drink wine. Once the dead is buried, the mourner is permitted to do so. So to on the Ninth of Av one is a mourner – once the day has ended one is permitted to do anything. Even though we are permitted, we must always have a sigh in our hearts until the Holy One returns to her. The Holy One said to them: by your lives! I burnt her, as it says “From above He has hurled fire into my bones…” (Lamentations 1:13) I will build her, as it says “Yet again will I rebuild you, then you shall be built, O virgin of Israel…” (Jeremiah 31:3) Zion said to Him: Behold, I have been sitting thus for many years! I have counted the days from old and I have not been redeemed, therefore I have despaired. She said that my master has abandoned me. And from where do we learn that Zion said this? From that which is written regarding it “And Zion said, ‘The Lord has forsaken me, and the Lord has forgotten me.’” (Isaiah 49:14) ... Another explanation. “And Zion said, ‘The Lord has forsaken me…” (Isaiah 49:14) What is written before this? “Sing, O heavens, and rejoice, O earth, and mountains burst out in song, for the Lord has consoled His people, and He shall have mercy on His poor.” (Isaiah 49:13) Once Zion saw that the prophet recalled His people and His poor, but did not mention Zion or Jerusalem she said ‘the Lord has forsaken me, and the Lord has forgotten me.’ Immediately the Holy One replied and said to her: just as it is impossible for a woman to forget her sucking child, so to I am not able to forget you, “Shall a woman forget her sucking child, from having mercy on the child of her womb?” (Isaiah 49:15) She said to Him: Master of the world! How is that possible? There is no end to the evils I have done! I caused Your Holy Temple to be destroyed and I killed the prophets. R’ Berachia the Kohen said in the name of Rebbe: the Holy One said to her, I will forget your evil but I will not forget your good. “…These too shall forget, but I will not forget you.” (ibid.) I have forgotten “"These are your gods, O Israel…” (Exodus32:4) but “I am the Lord, your God…” (Exodus 20:2) I will not forget.
