1 Samuel 24:3

And he took with him three thousand men, chosen out of all Israel, and went to seek David and his men in front of Saddaeem.

And he came to the sheepcotes by the way, where was a cave; and Saul went in to cover his feet: and David and his men remained in the sides of the cave.

He came to the sheep pens by the way, where there was a cave; and Saul went in to relieve himself. Now David and his men were staying in the innermost parts of the cave.
