1 Samuel 24:1-4

Now when Saul returned from pursuing the Philistines, he was told, saying, “Behold, David is in the wilderness of Engedi.” Then Saul took three thousand chosen men from all Israel and went to seek David and his men in front of the Rocks of the Wild Goats. He came to the sheepfolds on the way, where there was a cave; and Saul went in to relieve himself. Now David and his men were sitting in the inner recesses of the cave. The men of David said to him, “Behold, this is the day of which the LORD said to you, ‘Behold; I am about to give your enemy into your hand, and you shall do to him as it seems good to you.’ ” Then David arose and cut off the edge of Saul’s robe secretly.
