Yahweh said to Gideon, The people are yet too many; bring them down to the water, and I will try them for you there: and it shall be, that of whom I tell you, This shall go with you, the same shall go with you; and of whoever I tell you, This shall not go with you, the same shall not go.
So out from Mount Gilboa area there is this valley there. And the other side of the valley this little hill of Moreh. It isn't really a mountain but a hillside, and encamped in that valley was this huge host of the Midianites.
