1 Samuel 24:4-10

“Now’s your opportunity!” David’s men whispered to him. “Today the LORD is telling you, ‘I will certainly put your enemy into your power, to do with as you wish.’” So David crept forward and cut off a piece of the hem of Saul’s robe. But then David’s conscience began bothering him because he had cut Saul’s robe. He said to his men, “The LORD forbid that I should do this to my lord the king. I shouldn’t attack the LORD’s anointed one, for the LORD himself has chosen him.” So David restrained his men and did not let them kill Saul. After Saul had left the cave and gone on his way, David came out and shouted after him, “My lord the king!” And when Saul looked around, David bowed low before him. Then he shouted to Saul, “Why do you listen to the people who say I am trying to harm you? This very day you can see with your own eyes it isn’t true. For the LORD placed you at my mercy back there in the cave. Some of my men told me to kill you, but I spared you. For I said, ‘I will never harm the king—he is the LORD’s anointed one.’
