(4) Zadok and Abiathar . . . the priests.—Abiathar, though disgraced and practically deposed, was still regarded theoretically as priest (much as Annas is called “high priest” in the Gospels), for the priesthood was properly for life.

4:1-19 In the choice of the great officers of Solomon's court, no doubt, his wisdom appeared. Several are the same that were in his father's time. A plan was settled by which no part of the country was exhausted to supply his court, though each sent its portion.It is curious to find Abiathar in this list of princes, after what has been said of his disgrace 1 Kings 2:27, 1 Kings 2:35. Some have supposed that after a while Solomon pardoned him. Perhaps the true explanation is that the historian here enumerates all those who were accounted "princes" in any part of Solomon's reign. 4. Benaiah … was over the host—formerly captain of the guard. He had succeeded Joab as commander of the forces.

Zadok and Abiathar were the priests—Only the first discharged the sacred functions; the latter had been banished to his country seat and retained nothing more than the name of high priest.

i.e. The high priests, to wit, successively, first Abiathar, and then Zadok.

Quest. Why is Abiathar named when he was deposed?

Answ. First, Because it is ordinary for persons to retain the names and titles of those places which in reality they have lost. Secondly, Because though he was deposed from the high priesthood, yet he was a priest, and the chief of one of the priestly families: and as Zadok was jointly named with Abiathar, when Abiathar alone was the high priest, as 2 Samuel 8:17 20:25; so now Zadok and Abiathar are joined, although the high priesthood was rested in Zadok alone. Thirdly, Possibly Abiathar, though he was deposed from the supreme priesthood, yet upon his serious repentance, and by the intercession of his friends, was restored to the execution of the priestly office, and put into that place which Zadok enjoyed when Abiathar was high priest. Fourthly, Some say that here is mention made of all Solomon’s chief officers, both such as now were, and such as had been, and such as were afterwards, as they gather from 1 Kings 4:11,15, where two persons are named who married two of Solomon’s daughters, which could not be till many years after this time.

And Benaiah the son of Jehoiada was over the host,.... General of the army in the room of Joab, 1 Kings 2:35;

and Zadok and Abiathar were the priests; so they were when Solomon came to the throne; but Abiathar was deposed by him after some time, though he might retain the name afterwards, and be employed, as Ben Gersom thinks, in case of necessity, in the room of Zadok, or, however, be employed as a common priest at Jerusalem, upon a reconciliation with Solomon; though Kimchi thinks another Abiathar is meant, which is not so likely.

And Benaiah the son of Jehoiada was over the host: and Zadok and {c} Abiathar were the priests:

(c) Not Abiathar whom Solomon had put from his office, 1Ki 2:27 but another of that name.
