11 Then David took hold on his clothes, and tore them; and likewise all the men who were with him. 12 They mourned, and wept, and fasted until evening, for Saul, and for Jonathan his son, and for the people of Yahweh, and for the house of Israel; because they were fallen by the sword. 13 David said to the young man who told him, “Where are you from?”
He answered, “I am the son of a foreigner, an Amalekite.” 14 David said to him, “How were you not afraid to put forth your hand to destroy Yahweh’s anointed?” 15 David called one of the young men, and said, “Go near, and fall on him.” He struck him, so that he died. 16 David said to him, “Your blood be on your head; for your mouth has testified against you, saying, ‘I have slain Yahweh’s anointed.’”

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.
