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.)
13:8 Abram said to Lot, “Let there be no quarreling between me and you, and between my herdsmen and your herdsmen, for we are close relatives. 13:9 Is not the whole land before you? Separate yourself now from me. If you go to the left, then I’ll go to the right, but if you go to the right, then I’ll go to the left.”
13:10 Lot looked up and saw the whole region of the Jordan. He noticed that all of it was well-watered (before the Lord obliterated Sodom and Gomorrah) like the garden of the Lord, like the land of Egypt, all the way to Zoar. 13:11 Lot chose for himself the whole region of the Jordan and traveled toward the east.
So the relatives separated from each other.
