2 Samuel 20:8

Amasa went before them--Having collected some forces, he by a rapid march overtook the expedition at Gibeon, and assumed the place of commander; in which capacity, he was saluted, among others, by Joab.

Joab's garment, that he had put on was girded unto him--in the fashion of travellers and soldiers.

a sword . . . and as he went forth it fell out--that is, out of the scabbard. According to JOSEPHUS, he let it drop on purpose as he was accosting Amasa, that stooping, as it were accidentally, to pick it up, he might salute the new general with the naked sword in his hand, without exciting any suspicion of his design.

He went forth--in a ceremonious manner to meet Amasa, now commander-in-chief, in order to seem to render to that officer, whom he considered as usurping his post, a conspicuous honor and homage.

We have here Amasa's fall just as he began to rise. He was nephew to David (Sa2 17:25), had been Absalom's general and commander-in-chief of his rebellious army, but, that being routed, he came over into David's interest, upon a promise that he should be general of his forces instead of Joab. Sheba's rebellion gives David an occasion to fulfil his promise sooner than he could wish, but Joab's envy and emulation rendered its fulfillment of ill consequence both to him and David.
I. Amasa has a commission to raise forces for the suppressing of Sheba's rebellion, and is ordered to raise them with all possible expedition, Sa2 20:4. It seems, the men of Judah, though forward to attend the king's triumphs, were backward enough to fight his battles; else, when they were all in a body attending him to Jerusalem, they might immediately have pursued Sheba, and have crushed that cockatrice in the egg. But most love a loyalty, as well as a religion, that is cheap and easy. Many boast of their being akin to Christ that yet are very loth to venture for him. Amasa is sent to assemble the men of Judah within three days; but he finds them so backward and unready that he cannot do it within the time appointed (Sa2 20:5), though the promotion of Amasa, who had been their general under Absalom, was very obliging to them, and a proof of the clemency of David's government.
II. Upon Amasa's delay, Abishai, the brother of Joab, is ordered to take the guards and standing forces, and with them to pursue Sheba (Sa2 20:6, Sa2 20:7), for nothing could be of more dangerous consequence than to give him time. David gives these orders to Abishai, because he resolves to mortify Joab, and degrade him, not so much, I doubt, for the blood of Abner, which he had shed basely, as for the blood of Absalom, which he had shed justly and honourably. "Now (says bishop Hall) Joab smarteth for a loyal disobedience. How slippery are the stations of earthly honours and subject to continual mutability! Happy are those who are in favour with him in whom there is no shadow of change." Joab, without orders, though in disgrace, goes along with his brother, knowing he might be serviceable to the public, or perhaps now meditating the removal of his rival.
III. Joab, near Gibeon, meets with Amasa, and barbarously murders him, Sa2 20:8-10. It should seem, the great stone in Gibeon was the place appointed for the general rendezvous. There the rivals met; and Amasa, relying upon his commission, went before, as general both of the new-raised forces which he had got together, and of the veteran troops which Abishai had brought in; but Joab there took an opportunity to kill him with his own hand; and, 1. He did it subtilely, and with contrivance, and not upon a sudden provocation. He girded his coat about him, that it might not hang in his way, and girded his belt upon his coat, that his sword might be the readier to his hand; he also put his sword in a sheath too big for it, that, whenever he pleased, it might, upon a little shake, fall out, as if it fell by accident, and so he might take it into his hand, unsuspected, as if he were going to return it into the scabbard, when he designed to sheath it in the bowels of Amasa. The more there is of plot in a sin the worse it is. 2. He did it treacherously, and under pretence of friendship, that Amasa might not be upon his guard. He called him brother, for they were own cousins, enquired of his welfare (Art thou in health?) and took him by the beard, as one he was free with, to kiss him, while with the drawn sword in his other hand he was aiming at his heart. Was this done like a gentleman, like a soldier, like a general? No, but like a villain, like a base coward. Just thus he slew Abner, and went unpunished for it, which encouraged him to do the like again. 3. He did it impudently, not in a corner, but at the head of his troops, and in their sight, as one that was neither ashamed nor afraid to do it, that was so hardened in blood and murders that he could neither blush nor tremble. 4. He did it at one blow, gave the fatal push with a good-will, as we say, so that he needed not strike him again; with such a strong and steady hand he gave this one stroke that it was fatal. 5. He did it in contempt and defiance of David and the commission he had given to Amasa; for that commission was the only ground of his quarrel with him, so that David was struck at through the side of Amasa, and was, in effect, told to his face that Joab would be general, in spite of him. 6. He did it very unseasonably, when they were going against a common enemy and were concerned to be unanimous. This ill-timed quarrel might have scattered their forces, or engaged them one against another, and so have made them all an easy prey to Sheba. So contentedly could Joab sacrifice the interest both of king and kingdom to his personal revenge.
IV. Joab immediately resumes his general's place, and takes care to lead the army on in pursuit of Sheba, that, if possible, he might prevent any prejudice to the common cause by what he had done. 1. He leaves one of his men to make proclamation to the forces that were coming up that they were still engaged in David's cause, but under Joab's command, Sa2 20:11. He knew what an interest he had in the soldiery, and how many favoured him rather than Amasa, who had been a traitor, was now a turn-coat, and had never been successful; on this he boldly relied, and called them all to follow him. What man of Judah would not be for his old king and his old general? But one would wonder with what face a murderer could pursue a traitor; and how, under such a heavy load of guilt, he had courage to enter upon danger. Surely his conscience was seared with a hot iron. 2. care is taken to remove the dead body out of the way, because at that they made a stand (as Sa2 2:23), and to cover it with a cloth, Sa2 20:12, Sa2 20:13. Wicked men think themselves safe in their wickedness if they can but conceal it from the eye of the world: if it be hidden, it is with them as if it were never done. But the covering of blood with a cloth cannot stop its cry in God's ear for vengeance, or make it the less loud. However, since this was no time to arraign Joab for what he had done, and the common safety called for expedition, it was prudent to remove that which retarded the march of the army; and then they all went on after Joab, while David, who no doubt had notice soon brought him of this tragedy, could not but reflect upon it with regret that he had not formerly done justice upon Joab for the death of Abner, and that he now had exposed Amasa by preferring him. And perhaps his conscience reminded him of his employing Joab in the murder of Uriah, which had helped to harden him in cruelty.

Joab's garment - It appears that this was not a military garment; and that Joab had no arms but a short sword, which he had concealed in his girdle; and this sword, or knife, was so loose in its sheath that it could be easily drawn out. It is thought farther, that Joab, in passing to Amasa, stumbled, (for so some of the versions, and able critics, understand the words it fell out). and that the sword fell down when he stumbled; that he took it up with his left hand as if he had no bad intention; and then, taking Amasa by the beard with his right hand, pretending to kiss him, he, with his sword in his left hand, ripped up his bowels. This seems to be the meaning of this very obscure verse. It is worthy of remark that in the Eastern country it is the beard, not the man, which is usually kissed.

When they were at the great stone which is in Gibeon,.... Which, according to Josephus (r), was forty furlongs, or five miles from Jerusalem: what this great stone was, whether an obelisk, or what, is not certain; one of the greatest stones we read of was that which Semiramis cut out of the mountains of Armenia, which was an hundred thirty feet long, and twenty five broad and thick (s). This place was appointed for the rendezvous of David's forces, and hither Amasa came with what he had assembled together, and joined them, and took the command of them: for it follows:

Amasa went before them; as the general of them:

and Joab's garment that he had put on was girded unto him; who went along with his brother Abishai at the head of his own men, to which he was obliged by virtue of his commission; or went of himself to serve the common cause, and perhaps chiefly with a design to murder Amasa, whom he envied, because he was put into his post as general, and therefore accoutred himself for it; he put on, not a coat of mail, but a common garment which he girt about him, that it might be no incumbrance to him or hinderance of him, in doing what he intended, but that he might more expeditiously execute it:

and upon it a girdle with a sword fastened upon his loins in the sheath thereof; the sword in the belt was not on his thigh, but on his loins, on the outside of his clothes, and was put into a sheath too large, and placed in such a position, that with the least motion, when he pleased, it would easily drop out of it, without drawing it, and so give no suspicion of his design:

and as he went forth; to meet Amasa, just as he came to him:

it fell out; the sword fell out of the sheath to the ground.

(r) Antiqu. l. 7. c. 11. sect. 7. (s) Diodor. Sic. l. 2. p. 100. Vid. ib. p. 53. Herodot. Euterpe, c. 111.

Amasa went before them; having gathered some forces, and given due orders for the rest to follow him, he returned to Jerusalem, and by the king’ s command went after those mentioned ; and being come up to them at the place where they waited for him, he put himself into the head of Joab’ s men, and the Cherethites and the Pelethites, and such as he had brought along with him, and marched before them as their chief and general.

Girded unto him, after the manner of travellers and soldiers.

As he went forth to meet and salute Amasa, who was coming towards him to do him honour.

It fell out; things having (it is likely) been so contrived by Joab, that upon the least motion of his body his sword should drop out, and he might take it up without raising Amasa’ s suspicion.

Sheba's Rebellion. - Sa2 20:1. There happened to be a worthless man there, named Sheba, a Benjaminite. He blew the trumpet, and said, "We have no part in David, nor inheritance in the son of Jesse. Every man to his tents, O Israel!" "To his tents," i.e., to his home, as in Sa2 19:9, etc.
Sa2 20:2
All the men of Israel responded to this call, and went up (to the mountains) away from David and after Sheba; but the men of Judah adhered to their king from the Jordan to Jerusalem. The construction of דּבק with ועד ... מן is a pregnant one: they adhered to and followed him. The expression "from Jordan" does not prove that Sheba's rebellion broke out at the Jordan itself, and before David's arrival in Gilgal, but may be accounted for from the fact that the men of Judah had already fetched the king back across the Jordan.
Sa2 20:3
As soon as David returned to his palace at Jerusalem, he brought the ten concubines whom he had left behind, and with whom Absalom had lain, into a place of safety, and took care of them, without going in unto them any more. The masculine suffixes attached to יתּגם, יכלכּלם, and אליהם are used, as they frequently are, as being the more general and indefinite, instead of the feminine, which is the more definite form. Thus were they shut up in lifelong widowhood until the day of their death. אלמנוּת is an adverbial accusative, and חיּוּת signifies "condition in life;" literally, in widowhood of life.
Sa2 20:4
David then ordered Amasa to call the men of Judah to pursue Sheba the rebel, and attack him within three days, and then to present himself to him again. This commission was intended as the commencement of the fulfilment of the promise which David had given to Amasa (Sa2 19:14). It was no doubt his intention to give him the command over the army that marched against Sheba, and after the defeat of the rebel to make him commander-in-chief. But this first step towards the fulfilment 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.
Sa2 20:5-6
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, Sa2 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 Bttcher, who refers to Deu 32:10 and Zac 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.
Sa2 20:7
Thus there went after him (Abishai) Joab's men (the corps commanded by Joab), and the Crethi and Plethi (see at Sa2 8:18), out of Jerusalem, to pursue Sheba.
Sa2 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 (Sa2 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 Sa2 20:6, David had commissioned Abishai, Joab's brother, to pursue Sheba, and even in Sa2 20:7 Joab's men only are mentioned. This difficulty can hardly be solved in any other manner than by the simple assumption that David had told Abishai to go out with Joab, and that this circumstance is passed over in the brief account in Sa2 20:6, in which the principal facts alone are given, and consequently the name of Joab does not occur there. Clericus adopts the following explanation. "Mention," he says, "has hitherto been made simply of the command given to Abishai, but this included an order to Joab to go as well; and there is nothing to preclude the supposition that Joab's name was mentioned by the king, although this is not distinctly stated in the brief account before us."
(Note: This difficulty cannot be removed by emendations of the text, inasmuch as all the early translators, with the exception of the Syriac, had our Hebrew text before them. Thenius does indeed propose to alter Abishai into Joab in Sa2 20:6, after the example of Josephus and the Syriac; but, as Bttcher observes, if Joab had originally formed part of the text, it could not have been altered into Abishai either accidentally or intentionally, and the Syriac translators and Josephus have inserted Joab merely from conjecture, because they inferred from what follows that Joab's name ought to be found here. But whilst this is perfectly true, there is no ground for Bttcher's own conjecture, that in the original text Sa2 20:6 read as follows: "Then David said to Joab, Behold, the three days are gone: shall we wait for Amasa?" and through the copyist's carelessness a whole line was left out. For this conjecture has no tenable support in the senseless reading of the Cod. Vat., πρὸς Ἀμεσσαΐ́ for Ἀβισαΐ́.)
Sa2 20:9-10
Joab asked Amasa how he was, and laid hold of his bear with his right hand to kiss him. And as Amasa took no heed of the sword in Joab's hand, he smote him with it in the paunch (abdomen), and shed out his bowels upon the ground, "and repeated not (the stroke) to him" (cf. Sa1 26:8). Laying hold of the beard to kiss is still customary among Arabs and Turks as a sign of friendly welcome (vid., Arvieux, Merkwrdige Nachrichten, iv. p. 182, and Harmar, Beobachtungen, ii. p. 61). The reason for this assassination was Joab's jealousy of Amasa. Joab and Abishai then followed Sheba.
Sa2 20:11
One of Joab's attendants remained standing by him (Amasa), no doubt at Joab's command, and said to the people who came thither, i.e., to the men of Judah who were collected together by Amasa (vid., Sa2 20:4), "He that favoureth Joab, and he that (is) for David, let him (go) after Joab," i.e., follow him to battle against Sheba.
Sa2 20:12-13
Amasa lay wallowing in blood in the midst of the road; and when the man (the attendant) saw that all the people stood still (by the corpse), he turned (pushed) Amasa from the road to the field, and threw a cloth over him, whereupon they all passed by and went after Joab.
Sa2 20:14
But Joab "went through all the tribes of Israel to Abela, and Beth-maacah, and all Berim." Abela (Sa2 20:15), or Abel (Sa2 20:18), has been preserved in the large Christian village of Abil, a place with ruins, and called Abil-el-Kamh on account of its excellent wheat (Kamh), which lies to the north-west of Lake Huleh, upon a Tell on the eastern side of the river Derdra; not in Ibl-el-Hawa, a place to the north of this, upon the ridge between Merj Ayun and Wady et Teim (vid., Ritter, Erdk. xv. pp. 240, 241; Robinson, Bibl. Researches, pp. 372-3; and v. de Velde, Mem. p. 280). Beth-maacah was quite close to Abela; so that the names of the two places are connected together in Sa2 20:15, and afterwards, as Abel-beth-maacah (vid., Kg1 15:20, and Kg2 15:29), also called Abel-maim in Ch2 16:4. Berim is the name of a district which is unknown to us; and even the early translators did not know how to render it. There is nothing, however, either in the πάντες ἐν χαῤῥί is the lxx or the omnes viri electi of the Vulgate, to warrant an alteration of the text. The latter, in fact, rests upon a mere conjecture, which is altogether unsuitable; for the subject to ויּקּהלוּ cannot be כּל־הבּרים on account of the vav consec., but must be obtained from ישׂראל בּכל־שׁבטי. The Chethib ויקלהו is evidently a slip of the pen for ויּקּהלוּ.
Sa2 20:15
They besieged him (Sheba) in Abel-beth-maacah, and piled up a rampart against the city, so that it rose up by the town-moat (חל, the moat with the low wall belonging to it); and all the people with Joab destroyed to throw down the wall.
Sa2 20:16-18
Then a wise woman of the city desired to speak to Joab, and said (from the wall) to him (Sa2 20:18), "They were formerly accustomed to say, ask Abel; and so they brought (a thing) to pass." These words show that Abel had formerly been celebrated for the wisdom of its inhabitants.
Sa2 20:19
"I am of the peaceable, faithful in Israel: thou seekest to slay a city and mother in Israel; wherefore wilt thou destroy the inheritance of Jehovah?" The construing of אנכי with a predicate in the plural may be explained on the simple ground that the woman spoke in the name of the city as well as in its favour, and therefore had the citizens in her mind at the time, as is very evident from the figurative expression אם (mother) for mother-city or capital.
(Note: The correctness of the text is not to be called in question, as Thenius and Bttcher suppose, for the simple reason that all the older translators have followed the Hebrew text, including even the lxx with their ἐγώ εἰμι εἰρηνικὰ τῶν στηριγμάτων ἐν Ἰσραήλ; whereas the words ἅ ἔθεντο οἱ πιστοὶ τοῦ Ἰσραήλ, which some of the MSS contain at the close of Sa2 20:18 after ει ̓ ἐξέλιπον, and upon which Thenius and Bttcher have founded their conjectures, are evidently a gloss or paraphrase of התמּוּ וכן, and of so little value on critical grounds, that Tischendorf did not even think the reading worth mentioning in his edition of the Septuagint.)
The woman gave Joab to understand, in the first place, that he ought to have asked the inhabitants of Abela whether they intended to fight for Sheba before commencing the siege and destruction of the town, according to the law laid down in Deu 20:10. with reference to the siege of foreign towns; and secondly, that he ought to have taken into consideration the peaceableness and fidelity of the citizens of Abela, and not to destroy the peace-loving citizens and members of the nation of God.
Sa2 20:20
The woman's words made an impression upon Joab. He felt the truthfulness of her reproaches, and replied, "Far be it, far be it from me, to swallow up or destroy." אם, as in the case of oaths: "truly not."
Sa2 20:21
"It is not so (sc., as thou sayest), but a man of the mountains of Ephraim (which extended into the tribe of Benjamin: see at Sa1 1:1), Sheba the son of Bichri, hath lifted up his hand against the king David. Only give him up, and I will draw away from the city." The woman promised him this: "Behold, his head shall be thrown out to thee over the wall."
Sa2 20:22
She then came to all the people (i.e., the citizens of the town) "with her wisdom," i.e., with the wise counsel which she had given to Joab, and which he had accepted; whereupon the citizens cut off Sheba's head, and threw it out to Joab. Then Joab had a trumpet blown for a retreat, and the men disbanded, whilst he himself returned to Jerusalem to the king.
