Genesis 13:8

4 to the site where he had built the altar. And there Abram called on the name of the LORD.

5 Now Lot, who was traveling with Abram, also had flocks and herds and tents.

6 But the land was unable to support both of them while they stayed together, for they had so many possessions that they were unable to coexist.

7 And there was discord between the herdsmen of Abram and the herdsmen of Lot. At that time the Canaanites and the Perizzites were also living in the land.

8 So Abram said to Lot, “Please let there be no contention between you and me, or between your herdsmen and my herdsmen. After all, we are brothers.

9 Is not the whole land before you? Now separate yourself from me. If you go to the left, I will go to the right; if you go to the right, I will go to the left.”

10 And Lot looked out and saw that the whole plain of the Jordan, all the way to Zoar, was well watered like the garden of the LORD, like the land of Egypt. (This was before the LORD destroyed Sodom and Gomorrah.)

11 So Lot chose the whole plain of the Jordan for himself and set out toward the east. And Abram and Lot parted company.

12 Abram lived in the land of Canaan, but Lot settled in the cities of the plain and pitched his tent toward Sodom.
