1 Samuel 24:3-5

New Century Version

³ 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. ⁴ 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. ⁵ Later David felt guilty because he had cut off a corner of Saul’s robe.
