Genesis 13:5-7

And Lot, who went with Abram, also had flocks and herds and tents, so that the land could not support both of them dwelling together; for their possessions were so great that they could not dwell together, and there was strife between the herdsmen of Abram’s livestock and the herdsmen of Lot’s livestock. At that time the Canaanites and the Perizzites were dwelling in the land.
