Genesis 15:12-21

12And as the sun was just going down, a deep sleep fell upon Abram; and behold, a horror, a great darkness, fell upon him. 13And he said to Abram, Know assuredly that thy seed will be a sojourner in a land [that is] not theirs, and they shall serve them; and they shall afflict them four hundred years. 14But also that nation which they shall serve I will judge; and afterwards they shall come out with great property. 15And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. 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.
