SEV Biblia, Chapter 1:16
Y David le dijo: Tu sangre sea sobre tu cabeza, pues que tu boca atestiguó contra ti, diciendo: Yo maté al ungido del SEÑOR.
Clarke's Bible Commentary - 2 Samuel 1:16
Verse 16. Thy blood be upon thy head] If he killed Saul, as he said he did, then he deserved death; at that time it was not known to the contrary, and this man was executed on his own confession.
John Gill's Bible Commentary
Ver. 16. And David said unto him, thy blood [be] upon thy head , etc.] The blood that he had shed, let him suffer for it; for as he had shed blood, his blood ought to be shed, according to the law of God; and for proof of this, that he had so done, he appeals to his own confession: for thy mouth hath testified against thee, saying, I have slain the Lord’s anointed ; and what might serve to confirm the truth of what he had said were the crown and bracelet which he brought along with him; and besides he was an Amalekite, of a nation that was devoted to destruction; and, as Abarbinel thinks, David might suppose that he killed Saul to take vengeance on him for what he had done to their nation; but, after all, both he and Maimonides allow the punishment of him was not strictly according to law, but was a temporary decree, an extraordinary case, and an act of royal authority; for in common cases a man was not to be condemned and put to death upon his own confession, since it is possible he may not be in his right mind f14 ; but David chose to exercise severity in this case, partly to show his respect to Saul, and to ingratiate himself into the favour of his friends, and partly to deter men from attempting to assassinate princes, who himself was now about to ascend the throne.
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.
