Verses 12-13
2Sa 2:12-13War between the supporters of Ishbosheth and those of David. - 2Sa 2:12, 2Sa 2:13. When Abner had brought all Israel under the dominion of Ishbosheth, he also sought to make Judah subject to him, and went with this intention from Mahanaim to Gibeon, the present Jib, in the western portion of the tribe of Benjamin, two good hours to the north of Jerusalem (see at Jos 9:3), taking with him the servants, i.e., the fighting men, of Ishbosheth. There Joab, a son of Zeruiah, David's sister (1Ch 2:16), advanced to meet him with the servants, i.e., the warriors of David; and the two armies met at the pool of Gibeon, i.e., probably one of the large reservoirs that are still to be found there (see Rob. Pal. ii. pp. 135-6; Tobler, Topogr. v. Jerusalem, ii. pp. 515-6), the one encamping upon the one side of the pool and the other upon the other.
Verses 14-16
Abner then proposed to Joab that the contest should be decided by a single combat, probably for the purpose of avoiding an actual civil war. “Let the young men arise and wrestle before us.” שׂחק, to joke or play, is used here to denote the war-play of single combat. As Joab accepted this proposal, twelve young warriors for Benjamin and Ishbosheth, and twelve from David's men, went over, i.e., went out of the two camps to the appointed scene of conflict; “and one seized the other's head, and his sword was (immediately)in the side of the other (his antagonist), so that they fell together.” The clause רעהוּ בּצד וחרבּו is a circumstantial clause: and his sword (every one's sword) was in the side of the other, i.e., thrust into it. Sending the sword into the opponent's side is thus described as simultaneous with the seizure of his head. The ancient translators expressed the meaning by supplying a verb (ἐνέπηξαν, defixit: lxx, Vulg.). This was a sign that the young men on both sides fought with great ferocity, and also with great courage. The place itself received the name of Helkath-hazzurim, “field of the sharp edges,” in consequence (for this use of zur, see Psa 89:44).
Verses 17-19
As this single combat decided nothing, there followed a general and very sore or fierce battle, in which Abner and his troops were put to flight by the soldiers of David. The only thing connected with this, of which we have any further account, is the slaughter of Asahel by Abner, which is mentioned here (2Sa 2:18-23) on account of the important results which followed. Of the three sons of Zeruiah, viz., Joab, Abishai, and Asahel, Asahel was peculiarly light of foot, like one of the gazelles; and he pursued Abner most eagerly, without turning aside to the right or to the left.
Verses 20-22
Then Abner turned round, asked him whether he was Asahel, and said to him, “Turn to thy right hand or to thy left, and seize one of the young men and take his armour for thyself,” i.e., slay one of the common soldiers, and take his accoutrements as booty, if thou art seeking for that kind of fame. But Asahel would not turn back from Abner. Then he repeated his command that he would depart, and added, “Why should I smite thee to the ground, and how could I then lift up
