Genesis 13:5-9

Now Lot, who went with Abram, also had flocks and herds and tents. And the land could not sustain them while dwelling together, for their possessions were so great that they were not able to remain together. And there was strife between the herdsmen of Abram’s livestock and the herdsmen of Lot’s livestock. Now the Canaanite and the Perizzite were dwelling then in the land. 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.”
