"and it (the quail) covered the camp": I would not know to what extent. It is, therefore, written elsewhere (Numbers 11:31) "and about two cubits deep on the ground." And it was two cubits high above the ground so that a man standing (on the ground) could take it with ease. For (the distance) from his heart down is two cubits, and from his heart up, one cubit.
