Genesis 13:5-7
5
Lot also, who went with Abram, had flocks, and herds, and tents.
6
The land was not able to bear them, that they might live together: for their substance was great, so that they could not live together.
7
There was a strife between the herdsmen of Abram's livestock and the herdsmen of Lot's livestock: and the Canaanite and the Perizzite lived in the land at that time.
