'Fortified Cities' in the Bible

Where [can] we go up? Our brothers have {made our hearts melt}, {saying}, "The people are greater and taller than we are, [and there are] great fortified cities [reaching] up to heaven, and we saw the sons of the Anakites [living] there." '

All these, were fortified cities each with a high wall, folding gates and a bar, - besides country towns exceeding many.
