'Lowland' in the Bible

Abram went on living in the land of Canaan, and Lot went to the lowland towns, moving his tent as far as Sodom.

And when they had put them out, he said, Go for your life, without looking back or waiting in the lowland; go quickly to the mountain or you will come to destruction.

And he sent destruction on those towns, with all the lowland and all the people of those towns and every green thing in the land.

And looking in the direction of Sodom and Gomorrah and the lowland, he saw the smoke of the land going up like the smoke of an oven.

So it came about that when God sent destruction on the towns of the lowland, he kept his word to Abraham, and sent Lot safely away when he put an end to the towns where he was living.
