John Chrysostom

"When they traveled from the east, they found open country in the land of Sennar [Shinar] and settled there." Notice how the human race, instead of managing to keep to its own boundaries, always longs for more and reaches out for greater things. This is what the human race has lost in particular, not being prepared to recognize the limitations of its own condition but always lusting after more, entertaining ambitions beyond its capacity. In this regard, too, when people who chase after the things of the world acquire for themselves much wealth and status, they lose sight of their own nature, as it were, and aspire to such heights that they topple into the very depths. You could see this happening every day without others being any the wiser from the sight of it. Instead, they pause for a while but immediately lose all recollection of it and take the same road as the others and fall over the same precipice. This is exactly what you can see happening to these people in the present instance: "When they traveled from the east, they found open country in the land of Sennar [Shinar] and settled there." See how in gradual stages it teaches us the instability of their attitude. When they saw the open country (the text says), they packed up and left their previous dwelling and settled down there.
