Genesis 13:9

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 herdsmen of Abram’s cattle and the herdsmen of Lot’s cattle: and the Canaanite and the Perizzite dwelt 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 herdsmen and thy herdsmen; for we are brethren.

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

10 And Lot lifted up his eyes, and beheld all the Plain of the Jordan, that it was well watered every where, before Jehovah destroyed Sodom and Gomorrah, like the garden of Jehovah, like the land of Egypt, as thou goest unto Zoar.

11 So Lot chose him all the Plain of the Jordan; and Lot journeyed east: and they separated themselves the one from the other.

12 Abram dwelt in the land of Canaan, and Lot dwelt in the cities of the Plain, and moved his tent as far as Sodom.
