Genesis 13:9-11

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.
