Genesis 15:16-21

Then in the fourth generation your descendants shall return here [to Canaan, the land of promise], for the wickedness and guilt of the Amorites is not yet complete (finished).” [Josh 24:15] When the sun had gone down and a [deep] darkness had come, there appeared a smoking brazier and a flaming torch which passed between the [divided] pieces [of the animals]. [Jer 34:18, 19] On the same day the LORD made a covenant (promise, pledge) with Abram, saying, “To your descendants I have given this land, From the river of Egypt to the great river Euphrates— [the land of] the Kenites and the Kenizzites and the Kadmonites and the Hittites and the Perizzites and the Rephaim, the Amorites and the Canaanites and the Girgashites and the Jebusites.”
