11 After the death of Saul, David returned from his victory over the Amalekites and spent two days in Ziklag. 2 On the third day a man arrived from Saul's army camp. He had torn his clothes and put dirt on his head to show that he was in mourning. He fell to the ground before David in deep respect. 3 "Where have you come from?" David asked. "I escaped from the Israelite camp," the man replied. 4 "What happened?" David demanded. "Tell me how the battle went." The man replied, "Our entire army fled from the battle. Many of the men are dead, and Saul and his son Jonathan are also dead." 5 "How do you know Saul and Jonathan are dead?" David demanded of the young man. 6 The man answered, "I happened to be on Mount Gilboa, and there was Saul leaning on his spear with the enemy chariots and charioteers closing in on him. 7 When he turned and saw me, he cried out for me to come to him. 'How can I help?' I asked him. 8 "He responded, 'Who are you?' "'I am an Amalekite,' I told him. 9 "Then he begged me, 'Come over here and put me out of my misery, for I am in terrible pain and want to die.' 10 "So I killed him," the Amalekite told David, "for I knew he couldn't live. Then I took his crown and his armband, and I have brought them here to you, my lord."
11 David and his men tore their clothes in sorrow when they heard the news. 12 They mourned and wept and fasted all day for Saul and his son Jonathan, and for the Lord 's army and the nation of Israel, because they had died by the sword that day. 13 Then David said to the young man who had brought the news, "Where are you from?" And he replied, "I am a foreigner, an Amalekite, who lives in your land." 14 "Why were you not afraid to kill the Lord 's anointed one?" David asked. 15 Then David said to one of his men, "Kill him!" So the man thrust his sword into the Amalekite and killed him. 16 "You have condemned yourself," David said, "for you yourself confessed that you killed the Lord 's anointed one."

(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.
