Genesis 13:1-9 NIV
So Abram went up from Egypt to the Negev, with his wife and everything he had, and Lot went with him. Abram had become very wealthy in livestock and in silver and gold.
From the Negev he went from place to place until he came to Bethel, to the place between Bethel and Ai where his tent had been earlier and where he had first built an altar. There Abram called on the name of the LORD.
Now Lot, who was moving about with Abram, also had flocks and herds and tents. 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. And quarreling arose between Abram’s herders and Lot’s. The Canaanites and Perizzites were also living in the land at that time.
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. 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.”
