Genesis 13:1-12

So Abram went up out of Egypt, he and his wife and all that he had, and Lot [his nephew] with him, into the Negev (the South country of Judah). Now Abram was extremely rich in livestock and in silver and in gold. He journeyed on from the Negev as far as Bethel, to the place where his tent had been at the beginning, between Bethel and Ai, where he had first built an altar; and there Abram called on the name of the LORD [in prayer]. [Gal 3:6-9] But Lot, who went with Abram, also had flocks and herds and tents. Now the land was not able to support them [that is, sustain all their grazing and water needs] while they lived near one another, for their possessions were too great for them to stay together. And there was strife and quarreling between the herdsmen of Abram’s cattle and the herdsmen of Lot’s cattle. Now the Canaanite and the Perizzite were living in the land at that same time [making grazing of the livestock difficult]. So Abram said to Lot, “Please let there be no strife and disagreement between you and me, nor between your herdsmen and my herdsmen, because we are relatives. Is not the entire land before you? Please separate [yourself] from me. If you take the left, then I will go to the right; or if you choose the right, then I will go to the left.” So Lot looked and saw that the valley of the Jordan was well watered everywhere—this was before the LORD destroyed Sodom and Gomorrah; [it was all] like the garden of the LORD, like the land of Egypt, as you go to Zoar [at the south end of the Dead Sea]. Then Lot chose for himself all the valley of the Jordan, and he traveled east. So they separated from each other. Abram settled in the land of Canaan, and Lot settled in the cities of the valley and camped as far as Sodom and lived there.
