Genesis 13:5-7

13:5 Now Lot, who was traveling with Abram, also had flocks, herds, and tents. 13:6 But the land could not support them while they were living side by side. Because their possessions were so great, they were not able to live alongside one another. 13:7 So there were quarrels between Abram’s herdsmen and Lot’s herdsmen. (Now the Canaanites and the Perizzites were living in the land at that time.)
