Genesis 13:5-9

And Lot also, which went with Abram, had flocks, and herds, and tents.

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.

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.

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.

Is not the whole land before thee? separate thyself, I pray thee, from me: if thou wilt take the left hand, then I will go to the right; or if thou depart to the right hand, then I will go to the left.
