1 Now it came to pass after the death of Saul, when David was returned from the slaughter of the Amalekites, and David had abode two days in Ziklag; 2 It came even to pass on the third day, that, behold, a man came out of the camp from Saul with his clothes rent, and earth upon his head: and so it was, when he came to David, that he fell to the earth, and did obeisance. 3 And David said unto him, From whence comest thou? And he said unto him, Out of the camp of Israel am I escaped. 4 And David said unto him, How went the matter? I pray thee, tell me. And he answered, That the people are fled from the battle, and many of the people also are fallen and dead; and Saul and Jonathan his son are dead also. 5 And David said unto the young man that told him, How knowest thou that Saul and Jonathan his son be dead? 6 And the young man that told him said, As I happened by chance upon mount Gilboa, behold, Saul leaned upon his spear; and, lo, the chariots and horsemen followed hard after him. 7 And when he looked behind him, he saw me, and called unto me. And I answered, Here am I. 8 And he said unto me, Who art thou? And I answered him, I am an Amalekite. 9 And he said unto me again, Stand, I pray thee, upon me, and slay me: for anguish is come upon me, because my life is yet whole in me. 10 So I stood upon him, and slew him, because I was sure that he could not live after that he was fallen: and I took the crown that was upon his head, and the bracelet that was on his arm, and have brought them hither unto my lord. 11 Then David took hold on his clothes, and rent them; and likewise all the men that were with him: 12 And they mourned, and wept, and fasted until even, for Saul, and for Jonathan his son, and for the people of the LORD, and for the house of Israel; because they were fallen by the sword. 13 And David said unto the young man that told him, Whence art thou? And he answered, I am the son of a stranger, an Amalekite. 14 And David said unto him, How wast thou not afraid to stretch forth thine hand to destroy the LORD's anointed? 15 And David called one of the young men, and said, Go near, and fall upon him. And he smote him that he died. 16 And David said unto him, Thy blood be upon thy head; for thy mouth hath testified against thee, saying, I have slain the LORD's anointed. 17 And David lamented with this lamentation over Saul and over Jonathan his son: 18 (Also he bade them teach the children of Judah the use of the bow: behold, it is written in the book of Jasher.) 19 The beauty of Israel is slain upon thy high places: how are the mighty fallen! 20 Tell it not in Gath, publish it not in the streets of Askelon; lest the daughters of the Philistines rejoice, lest the daughters of the uncircumcised triumph. 21 Ye mountains of Gilboa, let there be no dew, neither let there be rain, upon you, nor fields of offerings: for there the shield of the mighty is vilely cast away, the shield of Saul, as though he had not been anointed with oil. 22 From the blood of the slain, from the fat of the mighty, the bow of Jonathan turned not back, and the sword of Saul returned not empty. 23 Saul and Jonathan were lovely and pleasant in their lives, and in their death they were not divided: they were swifter than eagles, they were stronger than lions. 24 Ye daughters of Israel, weep over Saul, who clothed you in scarlet, with other delights, who put on ornaments of gold upon your apparel. 25 How are the mighty fallen in the midst of the battle! O Jonathan, thou was slain in thine high places. 26 I am distressed for thee, my brother Jonathan: very pleasant hast thou been unto me: thy love to me was wonderful, passing the love of women. 27 How are the mighty fallen, and the weapons of war perished!
[AD 1781] Richard Challoner on 2 Samuel 1:1
This Book relates the transactions from the death of Saul until the end of David's reign, being a history for the space of about forty-six years.
[AD 1781] Richard Challoner on 2 Samuel 1:10
I killed him: This story of the young Amalecite was not true, as may easily be proved by comparing it with the last chapter of the foregoing book.
[AD 420] Jerome on 2 Samuel 1:14-16
Hence, “his blood will come upon him,” that is, he will be the cause of his own death, according to which principle David said to the one who had announced Saul’s death and had related that the king of Israel fell on his own sword: “Your blood be upon your head.” Not by my sentence, but by the blood of Saul will your blood be spilled.

[AD 430] Augustine of Hippo on 2 Samuel 1:14-16
But when no laws or lawful authorities give command, it is not lawful to kill another, even if he wishes and asks for it and has no longer the strength to live, as is clearly proved by the Scripture in the book of Kings [Samuel], where King David ordered the slayer of King Saul to be put to death, although he said that he had been importuned by the wounded and half-dead king to kill him with one blow and to free his soul struggling with the fetters of the body and longing to be released from those torments.

[AD 435] John Cassian on 2 Samuel 1:14-16
We know that David went beyond the precepts of the law when, despite Moses’ command to pay back one’s enemies in kind, he not only did not do this but even embraced his persecutors in love, prayed devoutly to the Lord on their behalf, even wept mournfully for them and revenged them when they were slain.

[AD 735] Bede on 2 Samuel 1:18
"And he commanded that the children of Judah be taught the bow, etc." [2 Samuel 1:18] This was written about David when he was mourning the deaths of Saul and Jonathan: And he commanded that the children of Judah be taught the bow, he did this because he knew that the Philistines abounded in archers, and Saul had perished particularly by their arrows, so he wanted his soldiers to learn the same art of war to defeat them. As for the following: As it is written in the book of the just, they assert that the very book cannot be found anywhere today, not even among the Hebrews, just as the book of the wars of the Lord mentioned in the book of Numbers; nor the songs of Solomon, nor his wisest discussions on the nature of trees, all herbs, likewise beasts, birds, reptiles, and fish; or what is said in the book of the Chronicles: The rest of Solomon's deeds, former and later, are written in the words of Nathan the prophet, and in the books of Ahijah the Shilonite. In the vision of Iddo the seer against Jeroboam son of Nebat (II Chron. IX), and many such volumes which are proven to have existed in Scripture but are acknowledged as no longer extant today. Judah was indeed ravaged by the Chaldeans, and even the library, formerly gathered, was consumed by enemy fire along with other provincial treasures. From this, the few books that now remain in the holy Scriptures were later restored through the efforts of Ezra the priest and prophet. Hence it is written about him: Ezra went up from Babylon, and he was a ready scribe in the law of Moses (I Esdras VII). Ready indeed, because he discovered quicker forms of letters than the Hebrews had up to that time. And in the letter of the king of Persia: Artaxerxes, king of kings, to Ezra the priest, the most learned scribe of the law of the God of heaven, greetings (Ibid.).

[AD 407] John Chrysostom on 2 Samuel 1:20
You have heard David’s lament for Saul.… If David did not wish the matter paraded in public so that it might not be a source of joy to his foes, so much the more must we avoid spreading the story to alien ears. Rather, we must not spread it even among ourselves for fear that our enemies may hear it and rejoice, for fear that our own may learn of it and fall. We must hush it up and keep it guarded on every side. Do not say to me, “I told so-and-so.” Keep the story to yourself. If you did not manage to keep quiet, neither will he manage to keep his tongue from wagging.

[AD 397] Ambrose of Milan on 2 Samuel 1:21
Nature, therefore, by withholding its gifts from those places which were to be witnesses of a parricidal act and by its condemnation of innocent soil, makes clear to us the severity of the future punishments of the guilty. The very elements are, therefore, condemned because of the crime of people. Hence David condemned the mountains, in which Jonathan and his father were slain, to be punished with perpetual sterility, saying, “You mountains of Gilboa, let neither dew nor rain come upon you, mountains of death.”

[AD 397] Ambrose of Milan on 2 Samuel 1:21
What a virtuous action was that when David wished rather to spare the king his enemy, though he could have injured him! How useful, too, it was, for it helped him when he succeeded to the throne. For all learned to observe faith in their king and not to seize the kingdom but to fear and reverence him. Thus, what is virtuous was preferred to what was useful, and then usefulness followed from what was virtuous. But that he spared him was a small matter; he also grieved for him when slain in war and mourned for him with tears, saying, “You mountains of Gilboa, let neither dew nor rain fall upon you; you mountains of death, for there the shield of the mighty is cast away, the shield of Saul. It is not anointed with oil but with the blood of the wounded and the fat of the warriors. The bow of Jonathan turned not back, and the sword of Saul returned not empty. Saul and Jonathan were lovely and very dear, inseparable in life, and in death they were not divided. They were swifter than eagles, they were stronger than lions. You daughters of Israel, weep over Saul, who clothed you in scarlet with your ornaments, who put on gold upon your apparel. How are the mighty fallen in the midst of the battle! Jonathan was wounded even to death. I am distressed for you, my brother Jonathan; very pleasant have you been to me. Your love came to me like the love of women. How have the mighty fallen and the longed-for weapons perished!” What mother could weep thus for her only son as he wept here for his enemy? Who could follow his benefactor with such praise as that with which he followed the man who plotted against his life? How affectionately he grieved, with what deep feeling he bewailed him! The mountains dried up at the prophet’s curse, and a divine power filled the judgment of him who spoke it. Therefore the elements themselves paid the penalty for witnessing the king’s death.

[AD 407] John Chrysostom on 2 Samuel 1:25-26
I will now cite from the Scriptures a wonderful instance of friendship. Jonathan, the son of Saul, loved David, and his soul was so knit to him that David in mourning over him says, “Your love to me was wonderful, passing the love of women. You were wounded fatally.” What then? Did Jonathan envy David? Not at all, though he had great reason. Why? Because, by the events he perceived that the kingdom would pass from himself to him, yet he felt nothing of the kind. He did not say, “This one is depriving me of my paternal kingdom,” but he favored David obtaining the sovereignty; and he didn’t spare his father for the sake of his friend. Yet let not any one think him a parricide, for he did not injure his father but restrained Saul’s unjust attempts. He rather spared than injured him. He did not permit Saul to proceed to an unjust murder. He was many times willing even to die for his friend, and far from accusing David, he restrained even his father’s accusation. Instead of envying, Jonathan joined in obtaining the kingdom for him. Why do I speak of wealth? He even sacrificed his own life for David. For the sake of his friend, he did not even stand in awe of his father, since his father entertained unjust designs, but his conscience was free from all such [things]. Thus justice was conjoined with friendship.Such then was Jonathan. Let us now consider David. He had no opportunity of returning the favor, for his benefactor was taken away before the reign of David and slain before he whom Jonathan had served came to his kingdom. What then? As far as it was allowed him and left in his power, let us see how that righteous man manifested his friendship. “Very pleasant,” he says, “have you been to me, Jonathan; you were wounded fatally.” Is this all? This indeed was no slight tribute, but he also frequently rescued from danger his son and his grandson, remembrance of the kindness of the father, and he continued to support and protect his children, as he would have done those of his own son. Such friendship I would wish all to entertain both toward the living and the dead.
