Genesis 15:3

And Abram said, Behold, to me Thou hast given no seed; and, lo, one born in my house is my heir. The promise which the Lord had given him, Genesis 12:2, seemed a thing of the far-distant past, and Abram's faith was sorely tried. Time was going on from day to day, from year to year, and still he was childless, without offspring, forsaken. There seemed to be but one conclusion possible, namely, that one of his house-slaves, his steward, Eliezer of Damascus, would be his heir. That is implied in the unfinished sentence, and the repetition of the same thought emphasizes the feeling of desolation which was stealing over the heart of Abram.
