Genesis 13:8-11

So Abram said to Lot, “Let’s not quarrel with each other, or between our herdsmen, since we are relatives. Look at the vast land that is in front of you! Let’s settle in different regions. If you choose the land on the left, then I’ll go right, and if you want land on the right, then I’ll go left.” Lot lifted his eyes and carefully surveyed the land around him all the way to Zoar. He noticed that the Jordan Valley was fertile and well-watered (this was before YAHWEH had destroyed Sodom and Gomorrah). It looked beautiful, like the garden of YAHWEH, or like Egypt. So Lot chose to settle in the Jordan Valley. He departed toward the east, and the family split up and separated from each other.
