Genesis 28:13-15

And, behold, Jehovah stood above it, and said, I am Jehovah, the God of Abraham thy father, and the God of Isaac: the land whereon 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. And, behold, I am with thee, and will keep thee whithersoever thou goest, and will bring thee again into this land; for I will not leave thee, until I have done that which I have spoken to thee of.
