15 Then David called one of his men and said, "Go, strike him down!" So he struck him down, and he died.
15 And David called one of the young men, and said, Go near, and fall upon him. And he smote him that he died.
15 Then David called one of the young men and said, "Go, execute him." And he struck him down so that he died.
15 Right then he ordered one of his soldiers, "Strike him dead!" The soldier struck him, and he died.
15 Then David called one of the young men and said, "Go near, and execute him!" And he struck him so that he died.
15 Then David said to one of his men, "Kill him!" So the man thrust his sword into the Amalekite and killed him.
Matthew Henry's Commentary on 2 Samuel 1:15
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.
