Genesis 15:2-5

MLV(i) 2 And Abram said, O Lord Jehovah, what will you give me, since I go childless. And he who will be possessor of my house is Eliezer of Damascus? 3 And Abram said, Behold, you have given no seed to me. And behold, a man born in my house is my heir.
4 And behold, the word of Jehovah came to him, saying, This man will not be your heir, but he who will come forth out of your own guts will be your heir.
5 And he brought him outside and said, Look now toward heaven and number the stars, if you are able to number them. And he said to him, So your seed will be.
