2 Samuel 1:15

11Then David took hold of his clothes and tore them; and all the men who were with him did likewise.

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

13David said to the young man who told him, “Where are you from?” He answered, “I am the son of a foreigner, an Amalekite.”

14David said to him, “Why were you not afraid to stretch out your hand to destroy the LORD’s anointed?”

15David called one of the young men and said, “Go near, and cut him down!” He struck him so that he died.

16David said to him, “Your blood be on your head, for your mouth has testified against you, saying, ‘I have slain the LORD’s anointed.’”

17David lamented with this lamentation over Saul and over Jonathan his son

18(and he commanded them to teach the children of Judah the song of the bow; behold, it is written in the book of Jashar):

19“Your glory, Israel, was slain on your high places! How the mighty have fallen!
