12 They grieved and mourned and fasted until evening for Saul and Jonathan and for Israel, the people of the Lord, because so many had been killed in battle.
13 David asked the young man who had brought him the news, “Where are you from?”He answered, “I'm an Amalekite, but I live in your country.”
14 David asked him, “How is it that you dared to kill the Lord's chosen king?”
15 Then David called one of his men and said, “Kill him!” The man struck the Amalekite and mortally wounded him,
16 and David said to the Amalekite, “You brought this on yourself. You condemned yourself when you admitted that you killed the one whom the Lord chose to be king.”
17 David sang this lament for Saul and his son Jonathan,
18 and ordered it to be taught to the people of Judah. (It is recorded in The Book of Jashar.)
