Genesis 13:5-7
5 Now Lot, who was moving about with Abram, also had flocks and herds and tents.
6 But the land could not support them while they stayed together, for their possessions were so great that they were not able to stay together.
7 And quarreling arose between Abram’s herdsmen and the herdsmen of Lot. The Canaanites and Perizzites were also living in the land at that time.
