2 Samuel 1:1-16

Now it happened after the death of Saul, when David had returned from the slaughter of the Amalekites, that he stayed two days in Ziklag. On the third day a man came [unexpectedly] from Saul’s camp with his clothes torn and dust on his head [as in mourning]. When he came to David, he bowed to the ground and lay himself face down [in an act of great respect and submission]. Then David asked him, “Where do you come from?” He said, “I have escaped from the camp of Israel.” David said to him, “How did it go? Please tell me.” He answered, “The people have fled from the battle. Also, many of the people have fallen and are dead; Saul and Jonathan his son are also dead.” So David said to the young man who informed him, “How do you know Saul and his son Jonathan are dead?” And the young man who told him explained, “By chance I happened to be on Mount Gilboa, and there was Saul leaning on his spear, and the chariots and horsemen [of the Philistines] were close behind him. When he turned to look behind him, he saw me, and called to me. And I answered, ‘Here I am.’ He asked me, ‘Who are you?’ I answered him, ‘I am an Amalekite.’ He said to me, ‘Stand up facing me and kill me, for [terrible] agony has come over me, yet I still live [and I will be taken alive].’ So I stood facing him and killed him, because I knew that he could not live after he had fallen. Then I took the crown which was on his head and the band which was on his arm, and I have brought them here to my lord.” [1 Sam 31:4] Then David grasped his own clothes and tore them [in mourning]; so did all the men who were with him. They mourned and wept and fasted until evening for Saul and Jonathan his son, and for the LORD’S people and the house of Israel, because they had fallen by the sword [in battle]. David said to the young man who informed him, “Where are you from?” He answered, “I am the son of a foreigner (resident alien, sojourner), an Amalekite.” David said to him, “How is it that you were not afraid to put out your hand to destroy the LORD’S anointed?” David called one of the young men and said, “Go, execute him.” So he struck the Amalekite and he died. David said to the [fallen] man, “Your blood is on your own head, for your own mouth has testified against you, saying, ‘I have killed the LORD’S anointed.’ ”
