1 Samuel 26:7-16

7So David and Abishai came to the people by night: and, behold, Saul lay sleeping within the trench, and his spear stuck in the ground at his head: but Abner and the people lay about him. 8Then said Abishai to David, God hath delivered thy enemy into thy hand this day: now therefore let me smite him, I pray thee, with the spear even to the earth at once, and I will not smite him the second time.1 9And David said to Abishai, Destroy him not: for who can stretch forth his hand against the LORD’S anointed, and be guiltless? 10David said furthermore, As the LORD liveth, the LORD shall smite him; or his day shall come to die; or he shall descend into battle, and perish. 11The LORD forbid that I should stretch forth my hand against the LORD’S anointed: but, I pray thee, take thou now the spear that is at his head, and the cruse of water, and let us go. 12So David took the spear and the cruse of water from beside Saul’s head; and they departed, and no man saw it, nor knew it, neither awoke: for they were all asleep; because a deep sleep from the LORD had fallen upon them.

13Then David went over to the other side, and stood on the top of an hill afar off; a great space being between them: 14And David cried to the people, and to Abner the son of Ner, saying, Answerest thou not, Abner? Then Abner answered and said, Who art thou that criest to the king? 15And David said to Abner, Art not thou a valiant man? and who is like thee in Israel? why then hast thou not kept thy lord the king? for there came in one of the people to destroy the king thy lord. 16This thing is not good that thou hast done. As the LORD liveth, ye are worthy to die, because ye have not kept your master, the LORD’S anointed. And now see where the king’s spear is, and the cruse of water that was at his head.2
