Genesis 13:7-8

And there was a strife between the herdsmen of Abram’s cattle and the herdsmen of Lot’s cattle: and the Canaanite and the Perizzite dwelt then in the land. And Abram said unto Lot, Let there be no strife, I pray thee, between me and thee, and between my herdsmen and thy herdsmen; for we are brethren.
