The Torah Speaks of Ideas
On the Kabbalistic reading of the verse "And Moses wrote their goings out according to their journeys" (Bamidbar 33:2), Rav Menahem Azariah writes: "The Torah speaks always of ideas when it seems to be describing concrete things: the higher meaning is the principal thing; the lower, material meaning holds the second place. Moses b. Nachman, indeed, follows another opinion in his commentary on Genesis in holding to the principle that 'the Torah speaks according to the manner of men'; but we can justly say that men speak according to the manner of the Torah."
