1 Samuel 24:4

So David’s men said to him, Behold this is the day, which the Lord mentioned to thee, that He would deliver thine enemy into thy hands, that thou mayst do to him what seemeth good in thine eyes. Then David arose, and cut off the skirt of Saul’s cloak privily.

And he came to the flocks of sheep that were by the way, and there was a cave there; and Saul went in to make preparation, and David and his men were sitting in the inner part of the cave.
