(Exodus 19:18) "And the whole of Mount Sinai smoked": I might think the place of the divine Presence alone; it is, therefore, written "the whole." "for the L–rd had come down upon it in fire": We are hereby apprised that the Torah is fire, that it was given from fire, and that it is comparable to fire, i.e., just as with fire, if one gets (too) close to it, he is burned, and if he is (too) far from it, he is chilled, so, (with Torah) one must "heat" himself only by its light, (and not in its "flames").
