Genesis 13:11

Then Lot chose him all the plain of Jordan.

In choosing this rich valley and excluding his uncle from it, Lot fancied that he had made. crafty choice. It was. selfish choice, an unwise choice, and the turning point of his own life downward. Henceforth misfortunes accumulate; he is made. captive by marauders and his property taken; he has to flee from Sodom to escape its fate and loses his wife; his history closes in shame. This plain is. great cleft from one to eight miles wide, by 120 long, and from 1000 to 2000 feet deep, lying at the Dead Sea 1316 feet below the level of the Mediterranean.

They separated themselves.

Abraham is henceforth separated from all earthly relations and stands by himself as the representative of his race in the land destined for them.
