이사야 1:8 탈무드 참조: Jerusalem Talmud Sukkah

MISHNAH: A sukkah which is higher than twenty cubits is disqualified; Rebbi Jehudah qualifies it¹Since the essence of a sukkah is its roofing, סְכָךְ, which has to be temporary and made from vegetable material, giving little protection from the rain, the roofing always should be visible to any person inside the sukkah.. It is disqualified if it is not ten hand-breadths high²Since nobody could dwell inside., or does not have three walls³Even though Isaias (Is. 1:8) gives the name of sukkah to a watchman’s shelter from the sun, a roof over 4 poles without any walls, this does not apply to the holiday hut which must be a dwelling place., or where the sunshine is larger than the shade.
