מדרש אויף ישעיהו 26:5

That the Sanhedrin were exiled a like number of times, we know by tradition. The places were as follows: from the cell of Gazith [in the Temple] to the market-place, from the market-place to Jerusalem, from Jerusalem to Yamnia, from Yamnia to Usha, from Usha [hack again] to Yamnia, (Ib. b) from Yamnia [back again] to Usha, from Usha to Shapram, from Shapram to Beth Shearim, from Beth Shearim to Sepphoris, from Sepphoris to Tiberias (and Tiberias was the saddest of them all; as it is said (Is. 29) And thou shalt be low, and shalt speak out of the earth). R. Elazar says they were exiled only six times, as it is said (Is. 26, 5) For he bringeth down them that dwell on high; the lofty city he layeth low; he layeth it low even to the ground; he bringeth it even to the dust. "Thence," remarked R. Jochanan, "they will in the future be redeemed, as it is said (Is. 52, 2) Shake thyself from the dust; arise, and sit down, etc."

For the conductor, on the hands of the dove. Yet my soul is silent only to God. This is what the scripture says (Isaiah 26:4), "Trust in the LORD forever, for the LORD, the LORD himself, is the Rock eternal." The Holy One, blessed be He, says, "Do you know in whom you trust? You trust in the One who created two worlds with two letters, as it says (Psalms 89:27), 'The God who is the Rock of Israel said, "I will be their Father."' And it says (Isaiah 43:10), 'Before me no god was formed, nor will there be one after me.'" This world was created with the letter "Heh." As it says (Genesis 2:4), "These are the generations of the heavens and the earth when they were created, on the day that the LORD God made earth and heaven." It says "Heh" - "they were created." And the World to Come was created with the letter "Yud." Therefore, it says, "The LORD is the Rock eternal," meaning, the world was created with His name. And why was this world created with the letter "Heh"? Just as when a person speaks the letter "Heh," there is no sensation of the lips or effort of the tongue, so too did the Holy One, blessed be He, create His world effortlessly and without toil, as it says (Psalms 33:6), "By the word of the LORD the heavens were made, their starry host by the breath of his mouth." And it says (Isaiah 57:15), "For this is what the high and exalted One says-- he who lives forever, whose name is holy: 'I live in a high and holy place, but also with the one who is contrite and lowly in spirit, to revive the spirit of the lowly and to revive the heart of the contrite.'" And afterwards, it says (Isaiah 26:5), "He will humble the haughty and bring down the exalted city; he will level it to the ground and destroy it completely." And afterwards (Micah 4:13), "Rise and thresh, Daughter Zion, for I will give you horns of iron; I will give you hooves of bronze, and you will break to pieces many nations." Thus said the Holy One, blessed be He, to Israel, "I am your Redeemer, but you must work. And what do I make you work on? On the laws and the courts that I have given you." Therefore, it says, "On the hands of the dove."
