Genesis 28:13-14

13And behold, the Lord stood above it and said: “I am the Lord God of Abraham your father and the God of Isaac; the land on which you lie I will give to you and your descendants.

14Also your descendants shall be as the dust of the earth; you shall spread abroad to the west and the east, to the north and the south; and in you and in your seed all the families of the earth shall be blessed.
