r.-ur, r.-ir (rehobhoth `ir, "Rehoboth City"; Septuagint he Rhohbos (Rhooboth) polis, "the city Rhoobos, Rhooboth"):

1. Probably Rebit Ninua:

The second of the cities built by Asshur (the Revised Version (British and American) by Nimrod) in Assyria (Ge 10:11,12). Unlike the other three, the exact equivalent of this name is not found in Assyrian literature Fried. Delitzsch points out (Wo lag das Paradies? 260 f) that rechobhoth is the equivalent of the Assyrian rebite, "streets," and suggests that the site referred to may be the Rebit Ninua, "streets of Nineveh," mentioned by Sargon of Assyria in connection with the peopling of Maganubba (Khorsabad or Dur-Sarru-kin; see Nineveh); and it was through this tract that Esar-haddon, his grandson, caused the heads of the kings of Kundi and Sidon to be carried in procession when he returned from his expedition to the Mediterranean.

2. Or, Possibly, the Old Capital, Assur:

Though the probabilities in favor of Rebit Ninua are great, it is doubtful whether a suburb could have been regarded as a foundation worthy of a primitive ruler, and that a very important city, Assur, the old capital of Assyria, would rather be expected. One of the groups expressing its name is composed of the characters Sag-uru, or, dialectically, Sab-eri, the second element being the original of the Hebrew `ir. As the "center-city," Assur may have been regarded as the city of broad spaces (rechobhoth)--its ruins are of considerable extent. The German explorers there have made many important discoveries of temples, temple- towers, palaces and streets, the most picturesque in ancient times being the twin tower-temples of Anu (the sky) and Adad (Hadad). The ruins lie on the Tigris, about 50 miles South of Nineveh. It practically ceased to be the capital about the middle of the 8th century BC.
