1 Samuel 26:6-11, 17-23

Then David said to Ahimelech the Hittite and to Abishai the son of Zeruiah, brother of Joab, “Who will go down with me to Saul in the camp?” And Abishai said, “I will go down with you.” So David and Abishai went to the army during the night, and there was Saul lying asleep inside the circle of the camp with his spear stuck in the ground by his head; and Abner and the people were lying around him. Then Abishai said to David, “God has given your enemy into your hand this day; now then, please let me strike him with the spear driving it to the ground with one stroke, and I will not strike him the second time.” But David said to Abishai, “Do not kill him, for who can put out his hand against the LORD’S anointed [king] and be guiltless (innocent)?” David also said, “As the LORD lives, most certainly the LORD will strike him [in His own time and way], or his day will come and he will die, or he will go down into battle and be carried off [dead]. The LORD forbid that I would put out my hand against the LORD’S anointed; but now take the spear that is by his head and the jug of water, and let us go.”

Then Saul recognized David’s voice and said, “Is this your voice, my son David?” And David said, “It is my voice, my lord the king!” And David said, “Why is my lord pursuing his servant? For what have I done? Or what evil is in my hand? Now therefore, please let my lord the king hear the words of his servant. If the LORD has incited you against me, let Him accept an offering [from me]; but if it is men, may they be cursed before the LORD, because they have driven me out this day to keep me from sharing in the inheritance of the LORD, saying, ‘Go, serve other gods.’ Now then, do not let my blood fall to the ground away from the presence of the LORD; for the king of Israel has come out to search for a single flea, just as when one hunts a [defenseless] partridge in the mountains.” Then Saul said, “I have sinned. Return, my son David, for I will not harm you again because my life was precious in your sight this day. Hear me, I have played the fool and have done a very great wrong [to you].” David answered, “Look, here is the king’s spear! Now let one of the young men come over and get it. The LORD will repay each man for his righteousness and his faithfulness; for the LORD handed you over to me today, but I refused to put out my hand against the LORD’S anointed.
