Oreb The Rock
O'reb, The Rock. The "raven's crag," the spot, east of Jordan, at which the Midianite chieftain, Oreb, with thousands of his countrymen, fell by the hand of the Ephraimites, and which, probably, acquired its name therefrom. It is mentioned in Judges 7:25; Isaiah 10:26. Perhaps, the place called 'Orbo, which in the Bereshith Rabba, is stated to have been in the neighborhood of Bethshean, may have some connection with it.
