2 Samuel 1:10-12

“So I killed him,” the Amalekite told David, “for I knew he couldn’t live. Then I took his crown and his armband, and I have brought them here to you, my lord.” David and his men tore their clothes in sorrow when they heard the news. They mourned and wept and fasted all day for Saul and his son Jonathan, and for the LORD’s army and the nation of Israel, because they had died by the sword that day.
