Adam Clarke on Genesis 13:11

Then Lot chose him all the plain - A little civility or good breeding is of great importance in the concerns of life. Lot either had none, or did not profit by it. He certainly should have left the choice to the patriarch, and should have been guided by his counsel; but he took his own way, trusting to his own judgment, and guided only by the sight of his eyes: he beheld all the plain of Jordan, that it was well watered, etc.; so he chose the land, without considering the character of the inhabitants, or what advantages or disadvantages it might afford him in spiritual things. This choice, as we shall see in the sequel, had nearly proved the ruin of his body, soul, and family.
