1 Samuel 26:17-19

17And 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.

18And he said, Why does my lord thus pursue after his servant? for what have I done? or what evil is in my hand?

19And now, I pray thee, let my lord the king hear the words of his servant. If Jehovah have moved thee against me, let him accept an oblation; but if the sons of men, cursed be they before Jehovah; for they have driven me out this day from adhering to the inheritance of Jehovah, saying, Go, serve other 1gods.
