Genesis 13:5-9

5And Lot also, who went with Abram, had flocks, and herds, and tents.

6And 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.

7And 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.

8And 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.

9Is 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 take the right hand, then I will go to the left.
