Midrasz do Zachariasza 11:1

Our Rabbis have been taught: Forty years before the destruction of the Temple, the lot never appeared in the right hand, the tongue of crimson wool did not become white, the westernmost light [of the candlestick in the Temple] did not burn, and the gates of the Temple opened by themselves, till R. Jochanan b. Zakkai uttered a rebuke, saying: "Temple! Temple! Why wilt thou be the alarm giver thyself [predicting thy own destruction]? We know that thou art destined to be destroyed, for, regarding thee Zechariah b. Ide hath prophesied (Zech. 11, 1) Open thy doors, O Lebanon, and the fire shall eat thy cedars."

(Ibid. 25) "Let me pass over, na and see": "na" is a term of imploration. "the good land" — Eretz Yisrael; "this good mountain" — the mountain of the King (i.e., Jerusalem); "and the Levanon" — the Temple. As it is written (Zechariah 11:1) "Open your doors, O Levanon," and (Isaiah 10:34) "And the Levanon will fall by a mighty one."...

... Teach us o teacher: toward where should one who prays orient his heart? This is what our Rabbis taught: one should orient his heart toward the place of the Holy of Holies (Berachot 4:5). R’ Eliezer ben Yaakov says: if one is praying outside of the land, he should orient his heart to the land of Israel. If one is praying within the land of Israel, he should orient his heart to Jerusalem. If one is praying in Jerusalem, he should orient his heart to the Holy Temple. If one is praying in the Holy Temple, he should orient his heart to the Holy of Holies. R’ Avin the Levi said: “our neck is like the Tower of David, built as a model (talpiyot)…” (Song of Songs 4:4) What does talpiyot mean? The hill (tel) toward which all turns (peniyot) are directed. And after all this praise, it is written “Open your doors, O Lebanon, and let the fire consume your cedars.” (Zechariah 11:1) And so too they said “He has hurled fire into my bones…” (Lamentations 1:13) Israel said to Him: Master of the World! How long will it be like this? Did You not write in Your Torah “…the one who ignited the fire shall surely pay” (Exodus 22:5)? And You are the one who ignited the fire, as it says “From above He has hurled fire into my bones…” (Lamentations 1:13) You need to rebuild it and to console us, not at the hands of an angel but You in Your glory. The Holy One said to them: by your life, so I will do! As it says “The Lord is the builder of Jerusalem; He will gather the outcasts of Israel.” (Psalms 147:2) And I am the one who consoles you. From where do we learn this? From that which they read in the prophets “I, yea I am He Who consoles you…” (Isaiah 51:12)
