Genesis 13:11-13

13:11 Lot chose for himself the whole region of the Jordan and traveled toward the east.

So the relatives separated from each other. 13:12 Abram settled in the land of Canaan, but Lot settled among the cities of the Jordan plain and pitched his tents next to Sodom. 13:13 (Now the people of Sodom were extremely wicked rebels against the Lord.)
