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.
13-15. David said unto the young man … Whence art thou?—The man had at the outset stated who he was. But the question was now formally and judicially put. The punishment inflicted on the Amalekite may seem too severe, but the respect paid to kings in the West must not be regarded as the standard for that which the East may think due to royal station. David's reverence for Saul, as the Lord's anointed, was in his mind a principle on which he had faithfully acted on several occasions of great temptation. In present circumstances it was especially important that his principle should be publicly known; and to free himself from the imputation of being in any way accessory to the execrable crime of regicide was the part of a righteous judge, no less than of a good politician.
