Here is, I. David's reception of these tidings. So far was he from falling into a transport of joy, as the Amalekite expected, that he fell into a passion of weeping, rent his clothes (Sa2 1:11), mourned and fasted (Sa2 1:12), not only for his people Israel and Jonathan his friend but for Saul his enemy. This he did, not only as a man of honour, in observance of that decorum which forbids us to insult over those that are fallen, and requires us to attend our relations to the grave with respect, whatever we lost by their life or got by their death, but as a good man and a man of conscience, that had forgiven the injuries Saul had done him and bore him no malice. He knew it, before his son wrote it (Pro 24:17, Pro 24:18), that if we rejoice when our enemy falls the Lord sees it, and it displeases him; and that he who is glad at calamities shall not go unpunished, Pro 17:5. By this it appears that those passages in David's psalms which express his desire of, and triumph in, the ruin of his enemies, proceeded not from a spirit of revenge, nor any irregular passion, but from a holy zeal for the glory of God and the public good; for by what he did here, when he heard of Saul's death, we may perceive that his natural temper was very tender, and that he was kindly affected even to those that hated him. He was very sincere, no question, in his mourning for Saul, and it was not pretended, or a copy of his countenance only. His passion was so strong, on this occasion, that it moved those about him; all that were with him, at least in complaisance to him, rent their clothes, and they fasted till even, in token of their sorrow; and probably it was a religious fast: they humbled themselves under the hand of God, and prayed for the repairing of the breaches made upon Israel by this defeat.

II.The reward he gave to him that brought him the tidings. Instead of preferring him, he put him to death, judged him out of his own mouth, as a murderer of his prince, and ordered him to be forthwith executed for the same. What a surprise was this to the messenger, who thought he should have favour shown him for his pains. In vain did he plead that he had Saul's order for it, that it was a real kindness to him, that he must inevitably have died; all those pleas are overruled: "Thy mouth has testified against thee, saying, I have slain the Lord's anointed (Sa2 1:16), therefore thou must die." Now,

1.David herein did not do unjustly. For, (1.) The man was an Amalekite. This, lest he should have mistaken it in his narrative, he made him own a second time, Sa2 1:13. That nation, and all that belonged to it, were doomed to destruction, so that, in slaying him, David did what his predecessor should have done and was rejected for not doing. (2.) He did himself confess the crime, so that the evidence was, by the consent of all laws, sufficient to convict him; for every man is presumed to make the best of himself. If he did as he said, he deserved to die for treason (Sa2 1:14), doing that which, it is probable, he heard Saul's own armour-bearer refuse to do; if not, yet by boasting that he had done it he plainly showed that if there had been occasion he would have done it, and would have made nothing of it; and, by boasting of it to David, he showed what opinion he had of him, that he would rejoice in it, as one altogether like himself, which was an intolerable affront to him who had himself once and again refused to stretch forth his hand against the Lord's anointed. And his lying to David, if indeed it was a lie, was highly criminal, and proved, as sooner or later that sin will prove, lying against his own head.

2.He did honourably and well. Hereby he demonstrated the sincerity of his grief, discouraged all others from thinking by doing the like to ingratiate themselves with him, and did that which might probably oblige the house of Saul and win upon them, and recommend him to the people as one that was zealous for public justice, without regard to his own private interest. We may learn from it that to give assistance to any in murdering themselves, directly or indirectly, if done wittingly, incurs the guilt of blood, and that the lives of princes ought to be, in a special manner, precious to us.

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.

And David said unto him, thy blood be upon thy head,.... 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 (n) 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 (o); 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.

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.
