Rehoboth in Easton's Bible Dictionary

broad places. (1.) A well in Gerar dug by Isaac (Gen. 26:22), supposed to be in Wady er-Ruheibeh, about 20 miles south of Beersheba. (2.) An ancient city on the Euphrates (Gen. 36:37; 1 Chr. 1:48), "Rehoboth by the river." (3.) Named among the cities of Asshur (Gen. 10:11). Probably, however, the words "rehoboth'ir" are to be translated as in the Vulgate and the margin of A.V., "the streets of the city," or rather "the public square of the city", i.e., of Nineveh.
