Genesis 15:13-21

Then the LORD said to Abram, “Know this for certain: Your offspring will be resident aliens for four hundred years in a land that does not belong to them and will be enslaved and oppressed. However, I will judge the nation they serve, and afterward they will go out with many possessions. But you will go to your ancestors in peace and be buried at a good old age. In the fourth generation they will return here, for the iniquity of the Amorites has not yet reached its full measure.” When the sun had set and it was dark, a smoking fire pot and a flaming torch appeared and passed between the divided animals. On that day the LORD made a covenant with Abram, saying, “I give this land to your offspring, from the Brook of Egypt to the great river, the Euphrates River: the land of the Kenites, Kenizzites, Kadmonites, Hethites, Perizzites, Rephaim, Amorites, Canaanites, Girgashites, and Jebusites.”
