1 Samuel 26:17 (KJV)

And David said to Abner, Art not thou a valiant man? and who is like to thee in Israel? wherefore then hast thou not kept thy lord the king? for there came one of the people in to destroy the king thy lord.

This 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 bolster.

And Saul knew David’s voice, and said, Is this thy voice, my son David? And David said, It is my voice, my lord, O king.

And he said, Wherefore doth my lord thus pursue after his servant? for what have I done? or what evil is in mine hand?

Now therefore, I pray thee, let my lord the king hear the words of his servant. If the Lord have stirred thee up against me, let him accept an offering: but if they be the children of men, cursed be they before the Lord; for they have driven me out this day from abiding in the inheritance of the Lord, saying, Go, serve other gods.
