of the promise was a very imprudent act, like the promise itself, since Joab, who had been commander of the army for so many years, was grievously offended by it; and moreover, being a well-tried general, he had incomparably more distinction in the tribe of Judah than Amasa, who had taken part in Absalom's rebellion and even led the rebel army, could possibly have.
Verses 5-6
But when Amasa stayed out beyond the time fixed for the execution of the royal commission (the Chethib וייחר is the Piel וייחר, whilst the Keri is either the Hiphil ויּוחר, or the imperfect Kal of יחר = אחר, cf. תּחז, 2Sa 20:9, and is quite unnecessary), probably because the men of Judah distrusted him, and were not very ready to respond to his summons, David said to Abishai, “Now will Sheba the son of Bichri be more injurious (more dangerous) to us than Absalom. Take thou the servants (soldiers) of thy lord and pursue after him, lest he reach fortified cities, and tear out our eye,” i.e., do us a serious injury. This is the correct explanation given by Böttcher, who refers to Deu 32:10 and Zec 2:12, where the apple of the eye is the figure used to signify the most valuable possession; for the general explanation, “and withdraw from our eye,” cannot be grammatically sustained.
Verse 7
2Sa 20:7Thus there went after him (Abishai) Joab's men (the corps commanded by Joab), and the Crethi and Plethi (see at 2Sa 8:18), out of Jerusalem, to pursue Sheba.
Verse 8
2Sa 20:8 “When they were by the great stone at Gibeon, and Amasa came to meet them (there), Joab was girded with his armour-coat as his clothing, and the girdle of the sword was bound over it upon his loins in its sheath, which came out, and it fell (i.e., the sheath came out of the sword-belt in which it was fastened, and the sword fell to the ground), Joab said to Amasa,” etc. The eighth verse contains only circumstantial clauses, the latter of which (from ויואב onwards) are subordinate to the earlier ones, so that ויּאמר (2Sa 20:9) is attached to the first clause, which describes the meeting between the advancing army and Amasa.
There is something striking, however, in the fact that Joab appears among them, and indeed, as we see from what follows, as the commander of the forces; for according to 2Sa 20:6, David had commissioned Abishai, Joab's brother, to pursue Sheba, and even in 2Sa 20:7 Joab's men only are mentioned. This difficulty can hardly be solved in any other manner than by the
