Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
O'REB (raven). The "rock of Oreb" was named after Oreb, one of the princes of Midian, whom the men of Ephraim slew. Jud 7:25; Isa 10:26. Reland and others would locate Oreb east of the Jordan and in the neighborhood of Bethshean, at a place called Orbo. It appears from Jud 8:4 that Gideon crossed the river in pursuit of the kings of Midian. Hence, Condor formerly suggested that the Midianite leaders were executed on the west side of the Jordan
and their heads carried to Gideon, on the other side, and that the rock Oreb was at Ash el-Ghorah. He adds: "The sharp peak overlooking the broad plain north of Jericho would indeed form a natural place for a public execution, which would be visible to the whole multitude beneath." - Palestine Quarterly, July, 1874, p. 184. In the Handbook of the Bible, however, he appears to have abandoned this identification, which leaves that of Reland as the
only probable location of Oreb suggested.
