II Samuel 1:10-12

So I stood over 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 bracelet that was on his arm, and have brought them here to my lord.” Therefore David took hold of his own clothes and tore them, and so did all the men who were with him. And they mourned and wept and fasted until evening for Saul and for Jonathan his son, for the people of the LORD and for the house of Israel, because they had fallen by the sword.
