Genesis 15:2-4

Darby Translation

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

³ And Abram said, Lo, to me thou hast given no seed, and behold, a son of my house will be mine heir.

⁴ And behold, the word of Jehovah [came] to him, saying, This shall not be thine heir, but he that will come forth out of thy body shall be thine heir.
