And it came to pass, after the year was expired, at the time when kings go forth to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem.

And it came to pass, at the return of the year, at the time when kings go out to battle , that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried at Jerusalem.

And it came to pass at the return of the year, at the time when kings go forth to war, that David sent Joab and his servants with him, and all Israel, and they spoiled the children of Ammon, and besieged Rabba: but David remained in Jerusalem.

And it came to pass, at the return of the year, at the time when kings go forth, that David sent Joab, and his servants with him, and all Israel; and they laid waste the land of the children of Ammon, and besieged Rabbah. But David abode at Jerusalem.

And it came to pass, at the return of the year, at the time when kings go out to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried at Jerusalem.

And it came to pass, after the year had expired, at the time when kings go forth to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and destroyed Rabbah. But David tarried still at Jerusalem.

And it cometh to pass, at the revolution of the year, at the time of the going out of the messengers, that David sendeth Joab, and his servants with him, and all Israel, and they destroy the Bene-Ammon, and lay siege against Rabbah. And David is dwelling in Jerusalem,

Now in the spring, at the time when kings go out to war, David sent Joab and his servants and all Israel with him; and they made waste the land of the children of Ammon, and took up their position before Rabbah, shutting it in. But David was still at Jerusalem.

Now it happened that, at the turn of the year, in the time when kings usually go forth to war, David sent Joab, and his servants with him, and all of Israel, and they laid waste to the sons of Ammon, and they besieged Rabbah. But David remained in Jerusalem.

After the year was expired - The next spring after the escape of the Ammonites into their city 2-Samuel 10:14.
The children of Ammon - The marginal reference supplies the word "the land of," which is obviously the right reading.
David tarried at Jerusalem - The Syrians being subdued, the war with Ammon was not of sufficient moment to require David's personal presence. The whole section relating to David's adultery and Uriah's death, from this verse to 2-Samuel 12:26, is omitted in the Book of Chronicles.

When kings go forth - This was about a year after the war with the Syrians spoken of before, and about the spring of the year, as the most proper season for military operations. Calmet thinks they made two campaigns, one in autumn and the other in spring; the winter being in many respects inconvenient, and the summer too hot.

And it came to pass, after the year was (a) expired, at the time when kings go forth [to battle], that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem.
(a) The year following about the spring time.

And it came to pass, that after the year was expired,.... Or at the end of the year, as the Targum, which concluded with the month Adar or February, the spring of the year:
at the time when kings go forth to battle; in the month Nisan, as the Targum on 1-Chronicles 20:1; adds, the same with Abib, which was the first month of the year, Exodus 12:2, a fit time to go out to war; when, as the Jewish commentators observe, the rains were over, and there were grass in the fields, and fruit on the trees, and corn ripe, and so food for horse and men. This month was called Nisan, as some think (d), from the military banners then erected; so by the Romans it is called Martius, and by us March, from Mars, the god of war; though some (e) take this to be the month Tisri, answering to part of September, and part of October, when all the fruits of the earth were gathered in, and supposed to be a fit time for war, when the heat of the year was declining:
that David sent Joab, and his servants with him, and all Israel; his whole army under Joab as general; in 1-Chronicles 20:1; it is "the power of the army"; the whole body of it: and they destroyed the children of Ammon; burnt their cities, and slew the inhabitants of them, and laid their land waste wherever they came:
and besieged Rabbah; their chief city, called Rabathamana by Polybius (f), that is, Rabbah of Ammon, and afterwards. Philadelphia, from Philadelphus, king of Egypt, as it was in the times of Jerom (g):
but David tarried still at Jerusalem; which is observed for the sake of the following history; it would have been well for him if he had gone forth with the army himself, then the sin he fell into would have been prevented.
(d) Vid. Bochart. Hierozoic. par. 1. l. 2. c. 50. col. 557. (e) Weemse of the Judicial Law, c. 28. p. 106. (f) Hist. l. 5. p. 414. (g) De loc. Hebrews. fol. 94. C.

Observe the occasions of David's sin; what led to it. 1. Neglect of his business. He tarried at Jerusalem. When we are out of the way of our duty, we are in temptation. 2. Love of ease: idleness gives great advantage to the tempter. 3. A wandering eye. He had not, like Job, made a covenant with his eyes, or, at this time, he had forgotten it. And observe the steps of the sin. See how the way of sin is down-hill; when men begin to do evil, they cannot soon stop. Observe the aggravations of the sin. How could David rebuke or punish that in others, of which he was conscious that he himself was guilty?

JOAB BESIEGES RABBAH. (2-Samuel 11:1)
at the time when kings go forth to battle--The return of spring was the usual time of commencing military operations. This expedition took place the year following the war against the Syrians; and it was entered upon because the disaster of the former campaign having fallen chiefly upon the Syrian mercenaries, the Ammonites had not been punished for their insult to the ambassadors.
David sent Joab and his servants . . . they destroyed the children of Ammon--The powerful army that Joab commanded ravaged the Ammonite country and committed great havoc both on the people and their property, until having reached the capital, they besieged Rabbah-- Rabbah denotes a great city. This metropolis of the Ammonites was situated in the mountainous tract of Gilead, not far from the source of the Arnon. Extensive ruins are still found on its site.

(Cf. 1-Chronicles 20:1). Siege of Rabbah. - "And it came to pass at the return of the year, at the time when the kings marched out, that David sent Joab, and his servants with him, and all Israel; and they destroyed the Ammonites and besieged Rabbah: but David remained in Jerusalem." This verse is connected with 2-Samuel 10:14, where it was stated that after Joab had put to flight the Aramaeans who came to the help of the Ammonites, and when the Ammonites also had fallen back before Abishai in consequence of this victory, and retreated into their fortified capital, Joab himself returned to Jerusalem. He remained there during the winter or rainy season, in which it was impossible that war should be carried on. At the return of the year, i.e., at the commencement of spring, with which the new years began in the month Abib (Nisan), the time when kings who were engaged in war were accustomed to open their campaign, David sent Joab his commander-in-chief with the whole of the Israelitish forces to attack the Ammonites once more, for the purpose of chastising them and conquering their capital. The Chethibh המּלאכים should be changed into המּלכים, according to the Keri and the text of the Chronicles. The א interpolated is a perfectly superfluous mater lectionis, and probably crept into the text from a simple oversight. The "servants" of David with Joab were not the men performing military service, or soldiers, (in which case "all Israel" could only signify the people called out to war in extraordinary circumstances), but the king's military officers, the military commanders; and "all Israel," the whole of the military forces of Israel. Instead of "the children of Ammon" we find "the country of the children of Ammon," which explains the meaning more fully. But there was no necessity to insert ארץ (the land or country), as השׁחית is applied to men in other passages in the sense of "cast to the ground," or destroy (e.g., 1-Samuel 26:15). Rabbah was the capital of Ammonitis (as in Joshua 13:25): the fuller name was Rabbath of the children of Ammon. It has been preserved in the ruins which still exist under the ancient name of Rabbat-Ammn, on the Nahr Ammn, i.e., the upper Jabbok (see at Deuteronomy 3:11). The last clause, "but David sat (remained) in Jerusalem," leads on to the account which follows of David's adultery with Bathsheba (vv. 2-27 and 2 Samuel 12:1-25), which took place at that time, and is therefore inserted here, so that the conquest of Rabbah is not related till afterwards (2-Samuel 12:26-31).

After - When that year ended, and the next begun, which was in the spring time. When kings - Which is, when the ground is fit for the march of soldiers, and brings forth provision for man and beast. Tarried at Jerusalem - Had he been now in his post, at the head of his forces be had been out of the way of temptation.
