Genesis 13:10-13

10So Lot looked and saw that the valley of the Jordan was well watered everywhere—this was before the Lord destroyed Sodom and Gomorrah; [it was all] like the garden of the Lord, like the land of Egypt, as you go to Zoar [at the south end of the Dead Sea].

11Then Lot chose for himself all the valley of the Jordan, and he traveled east. So they separated from each other.

12Abram settled in the land of Canaan, and Lot settled in the cities of the valley and camped as far as Sodom and lived there.

13But the men of Sodom were extremely wicked and sinful against the Lord [unashamed in their open sin before Him].
