Genesis 15:1-4

1After these events, the word of the Lord came to Abram in a vision: Do not be afraid, Abram. I am your shield; your reward will be very great.

2But Abram said, “Lord God, what can you give me, since I am childless and the heir of my house is Eliezer of Damascus?”

3Abram continued, “Look, you have given me no offspring, so a slave born in my house will be my heir.”

4Now the word of the Lord came to him: “This one will not be your heir; instead, one who comes from your own body will be your heir.”
