Genesis 13:5-8 King James Version (KJV)
5 And Lot also, which went with Abram, had flocks, and herds, and tents.
6 And the land was not able to bear them, that they might dwell together: for their substance was great, so that they could not dwell together.
7 And there was a strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle: and the Canaanite and the Perizzite dwelled then in the land.
8 And Abram said unto Lot, Let there be no strife, I pray thee, between me and thee, and between my herdmen and thy herdmen; for we be brethren.
