SEV Biblia, Chapter 1:15
Entonces llamó David a uno de los jóvenes, y le dijo: Llega, y mátalo. Y él lo hirió, y murió.
John Gill's Bible Commentary
Ver. 15. And David called one of the young men , etc.] His servants that attended on him: and said, go near, [and] fall upon him ; by smiting him with his sword: and he smote him, that he died ; his orders were instantly obeyed. Kings and generals of armies had great power in those times and countries to execute a man immediately, without any other judge or jury: what may serve, or David might think would serve, to justify him in doing this, is what follows.
Matthew Henry Commentary
Verses 11-16 - David was sincere in his mourning for Saul; and all with him humble themselves under the hand of God, laid so heavily upon Israel by thi defeat. The man who brought the tidings, David put to death, as murderer of his prince. David herein did not do unjustly; the Amalekit 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, a sooner or later that sin will prove, lying against himself. Hereb David showed himself zealous for public justice, without regard to his own private interest.
