Genesis 15:2-4

New Living Translation

² But Abram replied, “O Sovereign Lord, what good are all your blessings when I don’t even have a son? Since you’ve given me no children, Eliezer of Damascus, a servant in my household, will inherit all my wealth. ³ You have given me no descendants of my own, so one of my servants will be my heir.”

⁴ Then the Lord said to him, “No, your servant will not be your heir, for you will have a son of your own who will be your heir.”
