Charles Ellicott Commentary Genesis 13:5-6

"And Lot also, who went with Abram, had flocks, and herds, and tents. And the land was not able to bear them, that they might dwell together: for their substance was great, so that they could not dwell together." — Genesis 13:5-6 (ASV)

Lot: He, too, had possibly received presents in Egypt, for we find him rivalling his uncle in wealth; and the “tents” show that he had numerous followers and, like Abram, was the chief of a powerful clan. The repetition that “the land was not able to bear them,” and that “they could not dwell together,” implies that the difficulty had long been felt before it led to an open rupture.
