Genesis 15:1-4

After all these things, this word of GOD came to Abram in a vision: “Don’t be afraid, Abram. I’m your shield. Your reward will be grand!” Abram said, “GOD, Master, what use are your gifts as long as I’m childless and Eliezer of Damascus is going to inherit everything?” Abram continued, “See, you’ve given me no children, and now a mere house servant is going to get it all.” Then GOD’s Message came: “Don’t worry, he won’t be your heir; a son from your body will be your heir.”
