Deuteronomy 3:4

4. Threescore cities, all the region of Argob In every instance in which Argob is mentioned there is accompanying it the descriptive word חבל , rope. Our translators have rendered it “region” in one place and “country” in another. It evidently means a sharply defined border, as if measured by a line or rope. Porter’s Giant Cities of Bashan says: “It thus describes with singular accuracy and minuteness the rocky rampart which encircles the Lejah,” the modern name of Argob. The Argob is a vast field of basalt placed in the midst of a fertile plain. Its surface has an elevation of about thirty feet, and its border is clearly defined by a bank of broken cliffs. In this region were the sixty cities mentioned in the text.
