For the children of Israel walked forty years in the wilderness, until all the nation, even the men of war who came forth out of Egypt, were consumed, because they didn't listen to the voice of Yahweh: to whom Yahweh swore that he wouldn't let them see the land which Yahweh swore to their fathers that he would give us, a land flowing with milk and honey.
Which means a rolling, because God there rolled away that reproach of Egypt, which is a type of the flesh, and the life after the flesh. They longed for the flesh pots of Egypt. Egypt always is symbolic of living after the flesh and lusting after the flesh.
