Genesis 13:4-8

Unto the place of the altar, which he had made there at the first: and there Abram called on the name of the LORD.

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.
