1 And it came to pass after this, that David inquired of the LORD, saying, Shall I go up into any of the cities of Judah? And the LORD said unto him, Go up. And David said, Whither shall I go up? And he said, Unto Hebron. 2 So David went up thither, and his two wives also, Ahinoam the Jezreelitess, and Abigail Nabal's wife the Carmelite. 3 And his men that were with him did David bring up, every man with his household: and they dwelt in the cities of Hebron. 4 And the men of Judah came, and there they anointed David king over the house of Judah. And they told David, saying, That the men of Jabesh-gilead were they that buried Saul. 5 And David sent messengers unto the men of Jabesh-gilead, and said unto them, Blessed be ye of the LORD, that ye have shewed this kindness unto your lord, even unto Saul, and have buried him. 6 And now the LORD shew kindness and truth unto you: and I also will requite you this kindness, because ye have done this thing. 7 Therefore now let your hands be strengthened, and be ye valiant: for your master Saul is dead, and also the house of Judah have anointed me king over them. 8 But Abner the son of Ner, captain of Saul's host, took Ish-bosheth the son of Saul, and brought him over to Mahanaim; 9 And made him king over Gilead, and over the Ashurites, and over Jezreel, and over Ephraim, and over Benjamin, and over all Israel. 10 Ish-bosheth Saul's son was forty years old when he began to reign over Israel, and reigned two years. But the house of Judah followed David. 11 And the time that David was king in Hebron over the house of Judah was seven years and six months. 12 And Abner the son of Ner, and the servants of Ish-bosheth the son of Saul, went out from Mahanaim to Gibeon. 13 And Joab the son of Zeruiah, and the servants of David, went out, and met together by the pool of Gibeon: and they sat down, the one on the one side of the pool, and the other on the other side of the pool. 14 And Abner said to Joab, Let the young men now arise, and play before us. And Joab said, Let them arise. 15 Then there arose and went over by number twelve of Benjamin, which pertained to Ish-bosheth the son of Saul, and twelve of the servants of David. 16 And they caught every one his fellow by the head, and thrust his sword in his fellow's side; so they fell down together: wherefore that place was called Helkath-hazzurim, which is in Gibeon. 17 And there was a very sore battle that day; and Abner was beaten, and the men of Israel, before the servants of David. 18 And there were three sons of Zeruiah there, Joab, and Abishai, and Asahel: and Asahel was as light of foot as a wild roe. 19 And Asahel pursued after Abner; and in going he turned not to the right hand nor to the left from following Abner. 20 Then Abner looked behind him, and said, Art thou Asahel? And he answered, I am. 21 And Abner said to him, Turn thee aside to thy right hand or to thy left, and lay thee hold on one of the young men, and take thee his armour. But Asahel would not turn aside from following of him. 22 And Abner said again to Asahel, Turn thee aside from following me: wherefore should I smite thee to the ground? how then should I hold up my face to Joab thy brother? 23 Howbeit he refused to turn aside: wherefore Abner with the hinder end of the spear smote him under the fifth rib, that the spear came out behind him; and he fell down there, and died in the same place: and it came to pass, that as many as came to the place where Asahel fell down and died stood still. 24 Joab also and Abishai pursued after Abner: and the sun went down when they were come to the hill of Ammah, that lieth before Giah by the way of the wilderness of Gibeon. 25 And the children of Benjamin gathered themselves together after Abner, and became one troop, and stood on the top of an hill. 26 Then Abner called to Joab, and said, Shall the sword devour for ever? knowest thou not that it will be bitterness in the latter end? how long shall it be then, ere thou bid the people return from following their brethren? 27 And Joab said, As God liveth, unless thou hadst spoken, surely then in the morning the people had gone up every one from following his brother. 28 So Joab blew a trumpet, and all the people stood still, and pursued after Israel no more, neither fought they any more. 29 And Abner and his men walked all that night through the plain, and passed over Jordan, and went through all Bithron, and they came to Mahanaim. 30 And Joab returned from following Abner: and when he had gathered all the people together, there lacked of David's servants nineteen men and Asahel. 31 But the servants of David had smitten of Benjamin, and of Abner's men, so that three hundred and threescore men died. 32 And they took up Asahel, and buried him in the sepulchre of his father, which was in Bethlehem. And Joab and his men went all night, and they came to Hebron at break of day.
[AD 430] Augustine of Hippo on 2 Samuel 2:5
The martyrs of Christ in their strivings for truth have conquered this love of one’s flesh.… For, in all flesh that lacks life, the one who has left the body cannot be aware of injury to the lifeless body, nor can he who created it lose anything. But in the midst of what was being done to the bodies of the dead, although the martyrs were enduring them fearlessly with great fortitude, among the brothers there was great grief, because no opportunity was given to them to pay just dues at the burial of the saints.… And thus, although no misery came upon those who had been slain, in the dismemberment of their bodies, in the burning of their bones, in the scattering of their ashes, a great sorrow tortured those who were unable to bury anything of theirs, because they themselves in a certain manner felt for those who had no feeling in any manner, and where now there was no passion on the part of the one, there was wretched compassion on the part of the other.Those men were praised and called blessed by King David who had bestowed the merciful kindness of burial on the dry bones of Saul and Jonathan, in keeping with that wretched compassion which I have mentioned. But, pray tell, what compassion is bestowed on those who have no feeling? Or should one think that the unburied were not able to cross the infernal river? May this be far from the Christian belief! Otherwise, it worked out very badly for so great a multitude of martyrs whose bodies could not be buried, and for them truth emptily said, “Do not be afraid of those who kill the body and after that have nothing more that they can do,” if they were able to do them such wrongs as to prevent their crossing over to the desired places. But, without any doubt, this is exceedingly false, for it is no hindrance to the faithful to be denied burial of the bodies. Also, it is of no advantage if burial is granted to the godless. Why, then, are those men said to have done an act of mercy in burying Saul and his son and blessed by good King David for this, unless it is because the hearts of the compassionate are favorably affected when they are concerned over the well-being of other bodies of the dead? Or is it because of that love which keeps one from ever hating his own flesh that they do not wish such things to happen after their own death to their own bodies, so that what they wish to be done for them when they shall have no feeling they care to do for others who now have no feeling, while they themselves still have feeling?

[AD 1781] Richard Challoner on 2 Samuel 2:10
He reigned two years: Viz., before he began visibly to decline: but in all he reigned seven years and six months; for so long David reigned in Hebron.
[AD 604] Gregory the Dialogist on 2 Samuel 2:22-23
But when the easily angered so attack others that it is impossible to shun them, they should not be smitten with open rebuke but sparingly with a certain respectful forbearance. We shall prove this better by citing the example of Abner. Scripture has it that when Asahel attacked him with vehement and inconsiderate haste, Abner said to Asahel, “Go off and do not follow me, lest I be obliged to strike you to the ground.… But he refused to listen to him, and would not turn aside. Therefore, Abner struck him with his spear, with a back stroke in the groin, and thrust him through, and he died.” Of whom, then, did Asahel serve as a type, but of those who are driven headlong in a violent access of frenzy? Such people, when under the impulse of a like frenzy, are the more cautiously to be shunned, the more carried away they are in their madness. Therefore, too, Abner, who in our language is termed “lamp of the father,” fled: that is to say, if the teacher, whose tongue symbolizes the heavenly light of God, perceives the mind of a person to be carried away along the rugged path of frenzy and refrains from bandying words with such an angered one, he is like one unwilling to strike a pursuer. But when easily angered people will not restrain themselves under any consideration, and, as it were, like Asahel, do not refrain from their mad pursuit, then it is necessary for those who try to check them in their frenzy, not on any account to allow their anger to be aroused but to show all possible calmness; and let them suggest discreetly that which will, as it were, by a side stroke pierce their frenzied mind.Thus, when Abner made a stand against his pursuer, he pierced him, not with a direct thrust but with the reverse end of his spear. Of course, to strike with the sharp point is to oppose another with an attack of open rebuke, but to strike a pursuer with the reverse end of the spear is to touch the frenzied quietly and partially, and to overcome him, as it were, by sparing him. But Asahel falls down dead on the spot: that is, turbulent minds, on perceiving that they are shown consideration and, on the other hand, because they are touched in their hearts in consequence of being reasoned with calmly, fall down at once from the lofty place to which they had raised themselves. Those, therefore, who withdraw from their frenzied impulse under the stroke of gentleness, die, as it were, without being struck by the head of a spear.
