"The saga of Abraham unfolds between two landmarks, the exodus from “Ur of the Chaldeans” (Ur Kasdim) of the family, or clan, of Terah and “the purchase of” (or “the burials in”) the cave of Machpelah. Tradition seems particularly firm on this point. The Hebrew text, in fact, locates the departure specifically at Ur Kasdim, the Kasdim being none other than the Kaldu of the cuneiform texts at Mari. It is manifestly a migration of which one tribe is the centre. The leader of the movement is designated by name: Terah, who “takes them out” from Ur, Abram his son, Lot the son of Haran, another son of Terah, and their wives, the best known being Sarai, the wife of Abram. The existence of another son of Terah, Nahor, who appears later, is noted.
Most scholars agree that Ur Kasdim was the Sumerian city of Ur, today Tall al-Muqayyar (or Mughair), about 200 miles (300 km) southeast of Baghdad in lower Mesopotamia, which was excavated from 1922 to 1934. It is certain that the cradle of the ancestors was the seat of a vigorous polytheism whose memory had not been lost and
whose uncontested master in Ur was Nanna (or Sin), the Sumero-Akkadian moon god. “They served other gods,” Joshua, Moses’ successor, recalled, speaking to their descendants at Shechem.
After the migration from Ur (c. 2000 BCE), the reasons for which are unknown, the first important stopping place was Harran, where the caravan remained for some time. The city has been definitely located in upper Mesopotamia, between the Tigris and the Euphrates rivers, in the Balikh valley and can be found on the site of the modern Harran in Turkey. It has been shown that
Harran was a pilgrimage city, for it was a centre of the Sin cult and consequently closely related to the moon-god cult of Ur. The Mari tablets have shed new light on the patriarchal period, specifically in terms of the city of Harran.
There have been many surprising items in the thousands of
tablets found in the palace at Mari. Not only are the Ḫapiru (“Hebrews”) mentioned but so also remarkably are the Banu Yamina (“Benjaminites”). It is not that the latter are identical with the family of Benjamin, a son of Jacob, but rather that a name with such a biblical ring appears in these extrabiblical sources in the 18th century BCE. What seems beyond doubt is that these
Benjaminites (or Yaminites, meaning “Sons of the Right,” or “Sons of the South,” according to their habits of orientation) are always indicated as being north of Mari and in Harran, in the Temple of Sin."
Interestingly this south and right equivalency I had mentioned on another post about Deccan.
"Ultimately from the word for right, which facing east, becomes south."
