2 Samuel 1:5-10

5Then David said to the young man who told him, "How do you know that Saul and his son Jonathan are dead?"

6And the young man who told him said, "By chance I happened to be on Mount Gilboa, and there was Saul leaning on his spear, and behold, the chariots and the horsemen were close upon him.

7And when he looked behind him, he saw me, and called to me. And I answered, 'Here I am.'

8And he said to me, 'Who are you?' I answered him, 'I am an Amalekite.'

9And he said to me, 'Stand beside me and kill me, for anguish has seized me, and yet my life still lingers.'

10So I stood beside him and killed him, because I was sure that he could not live after he had fallen. And I took the crown that was on his head and the armlet that was on his arm, and I have brought them here to my lord."
