26. Joab fought against Rabbah—The time during which this siege lasted, since the intercourse with Bath-sheba, and the birth of at least one child, if not two, occurred during the progress of it, probably extended over two years.

     27. the city of waters—Rabbah, like Aroer, was divided into two parts—one the lower town, insulated by the winding course of the Jabbok, which flowed almost round it, and the upper and stronger town, called the royal city. "The first was taken by Joab, but the honor of capturing so strongly a fortified place as the other was an honor reserved for the king himself."

     28. 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.

     30. he took their king's crown from off his head—While the treasures of the city were given as plunder to his soldiers, David reserved to himself the crown, which was of rarest value. Its great weight makes it probable that it was like many ancient crowns, not worn, but suspended over the head, or fixed on a canopy on the top of the throne.

     31. he brought forth the people . . . and put them under saws, &c.—This excessive severity and employment of tortures, which the Hebrews on no other occasion are recorded to have practised, was an act of retributive justice on a people who were infamous for their cruelties (1Sa 11:2; Am 1:13).
