It is usually called "Ur of the Chaldees," Hebrews 9:7 Acts 7:4; and is located, with strong probability, in the north-west part of Mesopotamia. The city of Orfah, to which the Jews make pilgrimages as the birthplace of Abraham, is a flourishing town of 30,000 inhabitants, seventy-eight miles south-west of Diarbekir. Some, however, place Ur in Lower Chaldea, at extensive ruins now called Warka, in latitude 31 degrees 19' North, longitude 45 degrees 40' East.
