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 (Sa2 8:16-18), that of treasurer, or one over the tribute, for it was not till towards the latter end of his time...

And Sheva was scribe,.... Either the same with Benaiah, or he was dead or removed, and Sheva was put in his place, see Sa2 8:17, and Zadok and Abiathar were the priests; as before; See Gill on Sa2 8:17.
