'Within' in the Bible

David rose and went to the place where Saul was camped. David saw the place where Saul and Abner, his Commander-in-Chief, lay down. Saul was lying down within the encampment, and the army was camped all around him.

David told himself, "One of these days I'll perish by Saul's hand. There is nothing better for me to do than to escape to Philistine territory. Saul will give up searching for me anymore within the borders of Israel, so I'll escape from him."
