'Inner' in the Bible

He came to the sheepfolds beside the road. There was a cave there, and Saul went in to relieve himself. Now David and his men were sitting in the inner recesses of the cave.

Immediately, David went to the place where Saul had camped. He saw the place where Saul and Abner son of Ner, the general of his army, were lying down. Saul was lying inside the inner circle of the camp with the troops camped around him.

That night, David and Abishai came to the troops, and Saul was lying there asleep in the inner circle of the camp with his spear stuck in the ground by his head. Abner and the troops were lying around him.
