Genesis 13:11-15

So Lot chose for himself all the vicinity of the Jordan, and Lot journeyed eastward. So they separated from each other.

Abram settled in the land of Canaan, while Lot settled in the cities of the vicinity of the Jordan, and moved his tents as far as Sodom.

Now the men of Sodom were exceedingly wicked sinners against the Lord.

The Lord said to Abram, after Lot had separated from him, “Now raise your eyes and look from the place where you are, northward and southward, and eastward and westward;

for all the land which you see I will give to you and to your descendants forever.
