Where in the Torah does it specify that we should use an Etrog (citron) during the foliday of Sukkot. I always thought the Torah refered to a citrus but not specifically a etrog.
The Torah describes the fruit we should use on Sukkot with Hebrew words that roughly translate as “a handsome fruit of a tree.” It is not clear if that is a proper name of a fruit or a description. Either way, we know the translation of an Etrog from our tradition. If you question the accuracy of that tradition, realize that the translation of any word is really a tradition, and so we must rely on our tradition to properly fulfill the Torah.
