Genesis 13:10-11 (ESV)
10 And Lot lifted up his eyes and saw that the Jordan Valley was well watered everywhere like the garden of the Lord, like the land of Egypt, in the direction of Zoar. (This was before the Lord destroyed Sodom and Gomorrah.)
11 So Lot chose for himself all the Jordan Valley, and Lot journeyed east. Thus they separated from each other.
What did Lot do wrong here?
Was it being selfish and taking the best Abraham offered like many accuse Lot of doing?
