Genesis 13:5-9. NIV

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 herders and Lot’s. The Canaanites and Perizzites were also living in the land at that time.

8 So Abram said to Lot, “Let’s not have any quarreling between you and me, or between your herders and mine, for we are close relatives. 9 Is not the whole land before you? Let’s part company. If you go to the left, I’ll go to the right; if you go to the right, I’ll go to the left.”
