Verses 23-26 (2 Samuel 20:23-26)

Here is an account of the state of David?s court after his restoration. Joab retained the office of general, being too great to be displaced. Benaiah, as before, was captain of the guards. Here is one new office erected, which we had not (2 Sam. 8:16-18), that of treasurer, or one over the tribute, for it was not till towards the latter end of his time that David began to raise taxes. Adoram was long in this office, but it cost him his life at last, 1 Kgs. 12:18.
