In the time of the Messiah, Sukkot will still be observed. It is the quintessential messianic holiday of Judaism. The poet Danny Siegel expressed the Messianic thrust so very well with this beautiful poem.

“If you always assume / the man sitting next to you / is the Messiah / waiting for some simple human kindness–
You will soon come to weigh your words /and watch your hands.
And if he so chooses / Not to reveal himself / In your time–
It will not matter.
Danny Siegel  “And God Braided Eve’s Hair” (1976); “Unlocked Doors” (1983)
