And he saw in his sleep a ladder standing upon the earth, and the top thereof touching heaven: the angels also of God ascending and descending by it; And the Lord leaning upon the ladder, saying to him: I am the Lord God of Abraham thy father, and the God of Isaac; the land, wherein thou sleepest, I will give to thee and to thy seed. And thy seed shall be as the dust of the earth: thou shalt spread abroad to the west, and to the east, and to the north, and to the south: and IN THEE and thy seed all the tribes of the earth SHALL BE BLESSED. And I will be thy keeper whithersoever thou goest, and will bring thee back into this land: neither will I leave thee, till I shall have accomplished all that I have said.
Genesis 28:12-13
