2 Samuel 1:12-22 GW

12 They mourned, cried, and fasted until evening because Saul, his son Jonathan, the LORD's army, and the nation of Israel had been defeated in battle.
13 David asked the young man who had brought him the news, "Where are you from?" And the young man answered, "I'm an Amalekite, the son of a foreign resident."
14 David asked, "Why weren't you afraid to take it upon yourself to destroy the LORD's anointed king?"
15 Then David called one of [his] young men and told him, "Come here and attack him." David's young man executed him
16 while David said, "You are responsible for spilling your own blood. You testified against yourself when you said, 'I killed the LORD's anointed king.'"
17 David wrote this song of mourning for Saul and his son Jonathan.
18 He said, "Teach this kesheth to the people of Judah." (It is recorded in the Book of Jashar.)
19 "Your glory, Israel, lies dead on your hills. See how the mighty have fallen!
20 Don't tell the news in Gath. Don't announce the victory in the streets of Ashkelon, or the daughters of the Philistines will be glad, and the daughters of godless men will celebrate.
21 You mountains in Gilboa, may there be no dew or rain on you or on your slopes, because warriors' shields were tarnished there. Saul's shield was never rubbed with olive oil.
22 From the blood of those killed and the fat of the warriors, Jonathan's bow did not turn away, nor did Saul's sword return unused.
