Genesis 15:3

1After these things the LORD’s word came to Abram in a vision, saying, “Don’t be afraid, Abram. I am your shield, your exceedingly great reward.”

2Abram said, “Lord GOD, what will you give me, since I go childless, and he who will inherit my estate is Eliezer of Damascus?”

3Abram said, “Behold, you have given no children to me: and, behold, one born in my house is my heir.”

4Behold, the LORD’s word came to him, saying, “This man will not be your heir, but he who will come out of your own body will be your heir.”

5The LORD brought him outside, and said, “Look now toward the sky, and count the stars, if you are able to count them.” He said to Abram, “So your offspring will be.”
