Avram's Only Hope for God's Promise Is Coming True, Right?

Avram is the first born and has all the bartering ships here. He doesn't know how god's going to come through on his promise, but he is going to say, i'm going to let god figure out how he's going to make good on his promise. And then we see, at the end of the story, avram hasn't even looked up at all. So it's this really moving a tale about the character of ram and the way that he applies the lesson that he learned in the story just prior.
