And Abraham said to the eldest servant of his house [Eliezer of Damascus], who ruled over all that he had, I beg of you, put your hand under my thigh; [Gen. 15:2.]
And the servant took ten of his master's camels and departed, taking some of all his master's treasures with him; thus he journeyed to Mesopotamia [between the Tigris and the Euphrates], to the city of Nahor [Abraham's brother].
