God replied: Even so, your wife Sarah is to bear you a son, and you shall call him Isaac. It is with him that I will maintain my covenant as an everlasting covenant and with his descendants after him.
The same night the Lord appeared to him and said: I am the God of Abraham, your father. Do not fear, for I am with you. I will bless you and multiply your descendants for the sake of Abraham, my servant.
I will remember my covenant with Jacob, and also my covenant with Isaac; and also my covenant with Abraham I will remember. The land, too, I will remember.
