2 Samuel 1:10-12

10 "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."

11 [Therefore] David took hold of his own clothes and tore them, and [so did] all the men who [were] with him.

12 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.
