The Edomite king Saul's or Shaul's city (Genesis 36:37). As Edom never extended to the Euphrates' "river," probably an Assyrian invasion put Shaul from Rehoboth on the Edomite throne. There is still a Rahabeh on the right bank of the river, eight miles below the junction of the Khabour, and three miles W. of the river; four or five miles further down on the left bank is Rahbeth malik, "royal Rehoboth"; whether this be Shaul's city, or whether it be Rehoboth Ir, is uncertain (1 Chronicles 1:48).
