Genesis 15:4-6

Complete Jewish Bible

⁴ But the word of Adonai came to him: “This man will not be your heir. No, your heir will be a child from your own body.” ⁵ Then he brought him outside and said, “Look up at the sky, and count the stars — if you can count them! Your descendants will be that many!” ⁶ He believed in Adonai, and he credited it to him as righteousness.
