'Fortified Cities' in the Bible

and whether the land they live in is good or bad, and whether the cities they inhabit are like camps or fortified cities,

but we ourselves will be ready armed to go before the children of Israel, until we have brought them unto their place: and our little ones shall dwell in the fortified cities because of the inhabitants of the land.

and Beth-nimrah, and Beth-haran: fortified cities, and folds for sheep.
