R. Akiva says: "succoth" refers to the clouds of glory, as in (Isaiah 4:5) "And the L–rd will create on the entire base of Mount Zion and on all of its branchings a cloud by day and smoke with a glow of flaming fire by night, on all the glory, a canopy." This tells me only of the past. Whence do I derive (the same for) the time to come? From (Ibid. 6) "And it shall be a succah to shade the day", (Ibid. 35:10) "And the redeemed of the L–rd will return, etc." And the sages say: Succoth is a place, as in (Exodus 13:20) "And they journeyed from Succoth and they encamped in Etham." Just as Etham is a place, so, Succoth.
