(Bamidbar 11:31) "And a wind went forth from the L-rd and blew in (vayagaz) quail from the sea": We are hereby taught that it (the quail flock) "blossomed" like "puffs" of wool (gazim). "and it spread over the camp": Some say that it killed in its descent as it did in being eaten. "about a day's journey on one side": towards the north. "and a day's journey on the other side": towards the south. R. Shimon says: "about a day's journey here": from above; "and a day's journey there": from below. "and about two cubits above the face of the earth": It hovered above two cubits over the face of the earth, so that they could be easily gathered in.
