2 Samuel 1:10-12

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

11 Then David took hold on his clothes, and tore them, and likewise all the men who were with him.

12 And they mourned, and wept, and fasted until evening, for Saul, and for Jonathan his son, and for the people of LORD, and for the house of Israel, because they were fallen by the sword.
