Genesis 28:13-14

And behold, Jehovah stood above it. And he said, I am Jehovah, the God of Abraham, thy father, and the God of Isaac: the land on which thou liest, to thee will I give it, and to thy seed. And thy seed shall be as the dust of the earth, and thou shalt spread abroad to the west, and to the east, and to the north, and to the south; and in thee and in thy seed shall all the families of the earth be blessed.
