Genesis 13:8-11

So Abram said to Lot, “Please let there be no strife between you and me, nor between my herdsmen and your herdsmen, for we are brothers. Is not the whole land before you? Please separate from me; if to the left, then I will go to the right; or if to the right, then I will go to the left.” Lot lifted up his eyes and saw all the valley of the Jordan, that it was well watered everywhere—this was before the LORD destroyed Sodom and Gomorrah—like the garden of the LORD, like the land of Egypt as you go to Zoar. So Lot chose for himself all the valley of the Jordan, and Lot journeyed eastward. Thus they separated from each other.
