Genesis 14:13

Told Abram the Hebrew. A fugitive, probably one of Lot’s servants, arrived at Abram’s dwelling near Hebron with a report of what had happened. Here for the first time Abram is called “the Hebrew,” designating him a descendant of Eber. Eber’s descendants were to be found all over the ancient Orient in the second millennium B.C., and were called Habim in cuneiform inscriptions and ‘Apiru in Egyptian texts. As a descendant of Eber, Abram may have been known to the Amorites and Canaanites of Palestine as “the Hebrew.”

Confederate with Abram. The three Amorite brothers mentioned in this text as confederates of Abram were probably tribal heads. Abram had concluded with them a treaty of mutual assistance, as is seen from the designation they receive here, literally, “men of Abram’s covenant,” and from the fact that they aided Abram in his raid to rescue Lot.
