Genesis 15:16-21

16And [in the] fourth generation they shall come hither again; for the iniquity of the Amorites is not yet full. 17And it came to pass when the sun had gone down, and it was dark, that behold, there was a smoking furnace, and a flame of fire which passed between those pieces. 18On the same day Jehovah made a covenant with Abram, saying, Unto thy seed I give this land, from the river of Egypt to the great river, the river Euphrates; 19the Kenites, and the Kenizzites, and the Kadmonites, 20and the Hittites, and the Perizzites, and the Rephaim, 21and the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.
