Genesis 28:13-14

And, behold, the LORD stood above it and said, I AM the God of Abraham, thy father, and the God of Isaac; the land upon which thou dost lie, to thee will I give it and to thy seed; and thy seed shall be as the dust of the earth, and thou shalt multiply to the west and to the east and to the Aquilon and to the Negev; and in thee and in thy seed shall all the families of the earth be blessed.
