Мидраш к Йешайау 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."
