The Lord appeared to Abram and said, “I'm going to give this land to your descendants.” So Abram built an altar to the Lord there because that was where the Lord appeared to him.
“No, it's your wife Sarah who is going to have a son for you!” God replied. “You are to call him Isaac. I will keep my agreement with him and his descendants as an eternal agreement.
That night the Lord appeared to him and said, “I am the God of Abraham your father. Don't be afraid, for I am with you. I will bless you and give you many descendants for the sake of my servant Abraham.”
