1 Samuel 24:1-7

After Saul returned from chasing the Philistines, he was told, “David is in the Desert of En Gedi.” So he took three thousand chosen men from all Israel and began looking for David and his men near the Rocks of the Wild Goats. Saul came to the sheep pens beside the road. A cave was there, and he went in to relieve himself. Now David and his men were hiding far back in the cave. The men said to David, “Today is the day the LORD spoke of when he said, ‘I will give your enemy over to you. Do anything you want with him.’ ” Then David crept up to Saul and quietly cut off a corner of Saul’s robe. Later David felt guilty because he had cut off a corner of Saul’s robe. He said to his men, “May the LORD keep me from doing such a thing to my master! Saul is the LORD’s appointed king. I should not do anything against him, because he is the LORD’s appointed king!” David used these words to stop his men; he did not let them attack Saul. Then Saul left the cave and went his way.
