Genesis 15:1-6 New International Version (NIV)

The Lord’s Covenant With Abram

15 After this, the word of the Lord came to Abram in a vision:

² But Abram said, “Sovereign Lord, what can you give me since I remain childless and the one who will inherit^[c] 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.” ⁵ He took him outside and said, “Look up at the sky and count the stars—if indeed you can count them.” Then he said to him, “So shall your offspring^[d] be.”

⁶ Abram believed the Lord, and he credited it to him as righteousness.
