Genesis 15:1-4 New International Version (NIV)

1. After this, the word of the Lord came to Abram in a vision: “Do not be afraid, Abram. I am your shield, your very great reward. ”

2. But Abram said, “Sovereign Lord, what can you give me since I remain childless and the one who will inherit my estate is Eliezer of Damascus?”

3. And Abram said, “You have given me no children; so a servant in my household will be my heir.”

4. Then the word of the Lord came to him: “This man will not be your heir, but a son who is your own flesh and blood will be your heir.”
