Genesis 15:2-4

New Century Version

² But Abram said, “Lord God, what can you give me? I have no son, so my slave Eliezer from Damascus will get everything I own after I die.” ³ Abram said, “Look, you have given me no son, so a slave born in my house will inherit everything I have.”

⁴ Then the Lord spoke his word to Abram: “He will not be the one to inherit what you have. You will have a son of your own who will inherit what you have.”
