Genesis 13:5-9

Lot, who was traveling with Abram, had also become very wealthy with flocks of sheep and goats, herds of cattle, and many tents. But the land could not support both Abram and Lot with all their flocks and herds living so close together. So disputes broke out between the herdsmen of Abram and Lot. (At that time Canaanites and Perizzites were also living in the land.) Finally Abram said to Lot, “Let’s not allow this conflict to come between us or our herdsmen. After all, we are close relatives! The whole countryside is open to you. Take your choice of any section of the land you want, and we will separate. If you want the land to the left, then I’ll take the land on the right. If you prefer the land on the right, then I’ll go to the left.”
