The steward of Abraham's household was his servant Eliezer, and whence was his servant? When (Abraham) went forth from Ur of the Chaldees all the magnates of the kingdom came to give him gifts; and Nimrod took his first-born (son) Eliezer and gave him to (Abraham) as a perpetual slave.
When (Eliezer had thus) dealt kindly with Isaac, he set him free, and the Holy One, blessed be He, gave him his reward in this world, so that there should not be a reward for the wicked in the world to come; and He raised him to kingship, and he is Og, king of Bashan.
