If, as some have thought, these quails were the same in nature and genus as the locusts, which came up at the command of GOD into the land of Egypt, the blessing was doubly grateful: that what, in the one instance, proved so destructive, should in the other become so nourishing. Exodus 10:12-15.

31 And there went forth a wind from the LORD, and brought quails from the sea, and let them fall by the camp, as it were a day'sc journey on this side, and as it were a day's journey on the other side, round about the camp, and as it were two cubits high upon the face of the earth.
32 And the people stood up all that day, and all that night, and all the next day, and they gathered the quails: he that gathered least gathered ten homers: and they spread them all abroad for themselves round about the camp.
