Yahweh said to Joshua, This day have I rolled away the reproach of Egypt from off you. Therefore the name of that place was called Gilgal, to this day.
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.
