Genesis 15:13-21

And he said unto Abram, Know of a surety that thy seed shall be sojourners in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; and also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance. But thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. And in the fourth generation they shall come hither again: for the iniquity of the Amorite is not yet full. And it came to pass, that, when the sun went down, and it was dark, behold, a smoking furnace, and a flaming torch that passed between these pieces. In that day Jehovah made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: the Kenite, and the Kenizzite, and the Kadmonite, and the Hittite, and the Perizzite, and the Rephaim, and the Amorite, and the Canaanite, and the Girgashite, and the Jebusite.
