Esau learned that Isaac had blessed Jacob and sent him to Paddan Aram to get a wife there, and while blessing him commanded, "Don't marry a Canaanite woman,"
he went to Ishmael and married Mahalath the sister of Nebaioth and daughter of Ishmael, Abraham's son. This was in addition to the wives he already had.
He came to a certain place and camped for the night since the sun had set. He took one of the stones there, set it under his head and lay down to sleep.
Then GOD was right before him, saying, "I am GOD, the God of Abraham your father and the God of Isaac. I'm giving the ground on which you are sleeping to you and to your descendants.
Your descendants will be as the dust of the Earth; they'll stretch from west to east and from north to south. All the families of the Earth will bless themselves in you and your descendants.
Yes. I'll stay with you, I'll protect you wherever you go, and I'll bring you back to this very ground. I'll stick with you until I've done everything I promised you."
