He came to the sheep pens by the way, where was a cave; and Saul went in to cover his feet. Now David and his men were abiding in the innermost parts of the cave.
and David and his men remained in the sides of the cave; unseen and unobserved by Saul, even six hundred of them; nor need this seem strange, since in those parts of the world there were caves exceeding large, made so either by nature or art. Vansleb b speaks of a cave in Egypt so extraordinary large, that, without hyperbole, a thousand horses might there draw up in battle array, and of another larger than that; and Strabo says c, that towards Arabia and Iturea are mountains difficult to be passed, and in which are deep caves, one of which would hold four thousand men: and as the mouths of these caves were generally narrow, and the further parts of them large, and also dark, persons at the entrance of them could be seen, when those in the more remote parts could not; and this cave is said to be extremely dark d; which accounts for Saul's being seen when he came into the cave, whereas David and his men could not be seen by him.
