'Defence' in the Bible

Only rebel not ye against the LORD, neither fear ye the people of the land; for they are bread for us: their defence is departed from them, and the LORD is with us: fear them not.

and we -- we are armed hasting before the sons of Israel till that we have brought them in unto their place; and our infants have dwelt in the cities of defence because of the inhabitants of the land;

and Beth-Nimrah, and Beth-Haran, cities of defence, and sheepfolds.
