Genesis 15:2-4

King James Version

² And Abram said, Lord God, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?

³ And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.

⁴ And, behold, the word of the Lord came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.
