(Ibid. 20) "And they journeyed from Succoth and they encamped in Eitam." Just as Eitam is a place, so, Succoth. R. Akiva said "Succoth" refers to the clouds of glory, viz. (Isaiah 4:5-6) "For all the glory shall it cover. And a succah shall it be for shade by day." This tells me only of the past. Whence do I derive (the same for) time to come? From "And a succah shall it be for shade by day," and (Ibid. 35:10) "And the redeemed of the L–rd will return, and they will come to Zion with song, the joy of the world over their heads."
