'Walled' in the Bible

And what sort of land they are living in, if it is good or bad; and what their living-places are, tent-circles or walled towns;

Nevertheless the people be strong that dwell in the land, and the cities are walled, and very great: and moreover we saw the children of Anak there.

But the people of Reuben and Gad approached Moses and said, “We will build sheepfolds here for our flocks and [walled] cities for our children,

But we ourselves will be ready armed to go before the children of Israel till we have taken them to their place: but our little ones will be safe in the walled towns against the people of the land.

And Beth-nimrah and Beth-haran: walled towns and shut-in places for sheep.
