Genesis 13:5-13 ESV
And Lot, who went with Abram, also had flocks and herds and tents, so that the land could not support both of them dwelling together; for their possessions were so great that they could not dwell together, and there was strife between the herdsmen of Abram’s livestock and the herdsmen of Lot’s livestock. At that time the Canaanites and the Perizzites were dwelling in the land.
Then Abram said to Lot, “Let there be no strife between you and me, and between your herdsmen and my herdsmen, for we are kinsmen. Is not the whole land before you? Separate yourself from me. If you take the left hand, then I will go to the right, or if you take the right hand, then I will go to the left.” And Lot lifted up his eyes and saw that the Jordan Valley was well watered everywhere like the garden of the LORD, like the land of Egypt, in the direction of Zoar. (This was before the LORD destroyed Sodom and Gomorrah.) So Lot chose for himself all the Jordan Valley, and Lot journeyed east. Thus they separated from each other. Abram settled in the land of Canaan, while Lot settled among the cities of the valley and moved his tent as far as Sodom. Now the men of Sodom were wicked, great sinners against the LORD.
