'Fortified' in the Bible

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

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.
