'Fenced' in the Bible

only, surely the people which is dwelling in the land is strong; and the cities are fenced, very great; and also children of Anak we have seen there.

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

And Bethnimrah, and Bethharan, fenced cities: and folds for sheep.
