Genesis 28:13-14

and the LORD stood at its top. He said, “I am the LORD, the God of your grandfather Abraham and the God of your father Isaac. I will give you and your descendants the ground you are lying on. Your descendants will be like the dust of the earth, and you will spread out to the west, east, north, and south. All the families of the earth will pronounce blessings on one another using your name and that of your descendants.
