Genesis 13:11

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.

13 But the men of Sodom were wicked, sinning greatly against the LORD.

14 After Lot had departed, the LORD said to Abram, “Now lift up your eyes from the place where you are, and look to the north and south and east and west,

15 for all the land that you see, I will give to you and your offspring forever.
