Numbers 11:4

And the mixt multitude that was among them fell a lusting: and the children of Israel also wept again, and said, Who shall give us flesh to eat?

Mixed multitude ... fell a lusting. These consisted of Egyptians (see the note at Exodus 12:38). To dream of banquets and plenty of animal food in the desert becomes a disease of the imagination; and to this excitement of the appetite no people are more liable than the natives of Egypt. But the Israelites participated in the same feelings, and expressed dissatisfaction with the manna on which they had hitherto been supported, in comparison with the vegetable luxuries with which they had been regaled in Egypt.
