11 After the death of Saul, when David had returned from defeating the Amalekites, David remained two days in Ziklag. 2 On the third day, a man came from Saul's camp, with his clothes torn and dirt on his head. When he came to David, he fell to the ground and did obeisance. 3 David said to him, "Where have you come from?" He said to him, "I have escaped from the camp of Israel." 4 David said to him, "How did things go? Tell me!" He answered, "The army fled from the battle, but also many of the army fell and died; and Saul and his son Jonathan also died." 5 Then David asked the young man who was reporting to him, "How do you know that Saul and his son Jonathan died?" 6 The young man reporting to him said, "I happened to be on Mount Gilboa; and there was Saul leaning on his spear, while the chariots and the horsemen drew close to him. 7 When he looked behind him, he saw me, and called to me. I answered, "Here sir.' 8 And he said to me, "Who are you?' I answered him, "I am an Amalekite.' 9 He said to me, "Come, stand over me and kill me; for convulsions have seized me, and yet my life still lingers.' 10 So I stood over him, and killed him, for I knew that he could not live after he had fallen. I took the crown that was on his head and the armlet that was on his arm, and I have brought them here to my lord."
11 Then David took hold of his clothes and tore them; and all the men who were with him did the same. 12 They mourned and wept, and fasted until evening for Saul and for his son Jonathan, and for the army of the Lord and for the house of Israel, because they had fallen by the sword. 13 David said to the young man who had reported to him, "Where do you come from?" He answered, "I am the son of a resident alien, an Amalekite." 14 David said to him, "Were you not afraid to lift your hand to destroy the Lord's anointed?" 15 Then David called one of the young men and said, "Come here and strike him down." So he struck him down and he died. 16 David said to him, "Your blood be on your head; for your own mouth has testified against you, saying, "I have killed the Lord's anointed.' "

Commentary on 2 Samuel 1:1-10
(Read 2 Samuel 1:1-10)
The blow which opened David's way to the throne was given about the time he had been sorely distressed. Those who commit their concerns to the Lord, will quietly abide his will. It shows that he desired not Saul's death, and he was not impatient to come to the throne.
Commentary on 2 Samuel 1:11-16
(Read 2 Samuel 1:11-16)
David was sincere in his mourning for Saul; and all with him humbled themselves under the hand of God, laid so heavily upon Israel by this defeat. The man who brought the tidings, David put to death, as a murderer of his prince. David herein did not do unjustly; the Amalekite confessed the crime. If he did as he said, he deserved to die for treason; and his lying to David, if indeed it were a lie, proved, as sooner or later that sin will prove, lying against himself. Hereby David showed himself zealous for public justice, without regard to his own private interest.
