We have here an account of the conquest of Rabbah, and other cities of the Ammonites. Though this comes in here after the birth of David's child, yet it is most probable that it was effected a good while before, and soon after the death of Uriah, perhaps during the days of Bath-sheba's mourning for him. Observe, 1. That God was very gracious in giving David this great success against his enemies, notwithstanding the sin he had been guilty of just at that time when he was engaged in this war, and the wicked use he had made of the sword of the children of Ammon in the murder of Uriah. Justly might he have made that sword, thenceforward, a plague to David and his kingdom; yet he breaks it, and makes David's sword victorious, even before he repents, that this goodness of God might lead him to repentance. Good reason had David to own that God dealt not with him according to his sins, Psa 103:10. 2. That Joab acted very honestly and honourably; for when he had taken the city of waters, the royal city, where the palace was, and from which the rest of the city was supplied with water (and therefore, upon the cutting off of that, would be obliged speedily to surrender), he sent to David to come in person to complete this great action, that he might have the praise of it, Sa2 12:26-28. Herein he showed himself a faithful servant, that sought his master's honour, and his own only in subordination to his, and left an example to the servants of the Lord Jesus, in every thing they do, to consult his honour. Not unto us, but to thy name, give glory. 3. That David was both too haughty and too severe upon this occasion, and neither so humble nor so tender as he should have been. (1.) He seems to have been too fond of the crown of the king of Ammon, Sa2 12:30. Because it was of extraordinary value, by reason of the precious stones with which it was set, David would have it set upon his head, though it would have been better to have cast it at God's feet, and at this time to have put his own mouth in the dust, under guilt. The heart that is truly humbled for sin is dead to worldly glory and looks upon it with a holy contempt. (2.) He seems to have been too harsh with his prisoners of war, Sa2 12:31. Taking the city by storm, after it had obstinately held out against a long and expensive siege, if he had put all whom he found in arms to the sword in the heat of battle, it would have been severe enough; but to kill them afterwards in cold blood, and by cruel tortures, with saws and harrows, tearing them to pieces, did not become him who, when he entered upon the government, promised to sing of mercy as well as judgment, Psa 101:1. Had he made examples of those only who had abused his ambassadors, or advised or assisted in it, that being a violation of the law of nations, it might have been looked upon as a piece of necessary justice for terror to other nations; but to be thus severe with all the cities of the children of Ammon (that is, the garrisons or soldiers of the cities) was extremely rigorous, and a sign that David's heart was not yet made soft by repentance, else the bowels of his compassion would not have been thus shut up - a sign that he had not yet found mercy, else he would have been more ready to show mercy.

And have taken the city of waters - The city where the tank or reservoir was that supplied the city and suburbs with water. Some think that the original, לכדתי את עיר המים lachadti eth ir hammayim, should be translated I have intercepted, or cut off, the waters of the city: and Houbigant translates the place, et aquas ab urbe jam derivavi; "And I have already drawn off the waters from the city." This perfectly agrees with the account in Josephus, who says των τε ὑδατων αυτους αποτεμνομενος, having cut off their waters, Antiq., lib. vii., cap. 7. This was the reason why David should come speedily, as the citadel, deprived of water, could not long hold out.

And he took their king's crown from off his head,.... The crown of Hanun the king of the Ammonites, who now fell into his hands, and whom he stripped of his ensigns of royalty, who had so shamefully abused his ambassadors, Sa2 10:4,

(the weight whereof was a talent of gold with the precious stones): or, "and a precious stone"; there might be more, as our version suggests, but there was one in it remarkably large and valuable; Josephus (b) says it had in it a very precious stone, a sardonyx; and this, according to the Talmud (c) was of the value of a talent of gold. A talent was equal to three thousand shekels, as appears from Exo 38:25; and was in value, according to Brerewood (d) of our money, 4500 pounds; but according to Bishop Cumberland (e) 5067 pounds, three shillings and ten pence. This crown was of the same value with the golden candlestick in the tabernacle, Exo 25:39; and some think that value here is meant, and not the weight, a talent of gold being very heavy; according to Bishop Cumberland (f), ninety three and three quarter pounds; some say an hundred thirteen pounds ten ounces, and more; too great a weight to be borne on the head by Hanun or David; but, what with the gold and precious stones about it, it might be equal in value to a talent of gold; but weight is expressly mentioned, and the crowns of the eastern princes were of great bulk and weight, as well as value: Athenaeus (g) makes mention of one made of ten thousand pieces of gold, placed on the throne of King Ptolemy, and of some of two cubits, of six, yea, of sixteen cubits. Some (h) are of opinion that this crown was not the crown of the king of Ammon, but of Milcom or Molech, their idol, and that the proper name should be retained in the version, and that David had a crown made of it he could bear; but if, as others (i), the Syriac talent is meant, which was but the fourth part of an Hebrew one, the difficulty is greatly lessened; for it seems to be the same crown David afterwards wore, as follows:

and it was set on David's head; to show that the kingdom was translated to him, or was become subject to him; as Alexander, on the conquest of Darius, put the Persian diadem on his own head (k), in token of that monarchy being translated to him: though, after all, the phrase, "from off", may be rendered "from above" or "over" (l) his head, and so it was set "above" or "over" the head of David, being supported by some means or other, that its weight did not bear thereon however, Paschalius, who wrote a learned work, "De Coronis", must be mistaken when be says (m) this seems to be the first use of a crown in the kingdom of Judah, there being no mention of a crown before, either of Saul or David, only of anointing; since express mention is made of Saul's crown, Sa2 1:10; though his observation may be just, that this crown, allowed to be worn by David, was a pledge of the renewal of his royal dignity, and of his acceptance with God upon his repentance for his above sins:

and he brought forth the spoil of the city in great abundance; which, or at least part of it, was dedicated to the building of the sanctuary, Sa2 8:11.

encamp against the city, and take it--It has always been characteristic of Oriental despots to monopolize military honors; and as the ancient world knew nothing of the modern refinement of kings gaining victories by their generals, so Joab sent for David to command the final assault in person. A large force was levied for the purpose. David without much difficulty captured the royal city and obtained possession of its immense wealth.

lest I take the city, and it be called after my name--The circumstance of a city receiving a new name after some great person, as Alexandria, Constantinople, Hyderabad, is of frequent occurrence in the ancient and modern history of the East.
