Azariah - was over the officers - He had the superintendence of the twelve officers mentioned below; see 1 Kings 4:7.
Zabud - was principal officer - Perhaps what we call premier, or prime minister.
The king's friend - His chief favourite - his confidant.
The son of Nathan - It is uncertain whether the Nathan of this verse is the prophet or the son of David 2 Samuel 5:14. While on the one hand the position of “king‘s friend” is more likely to have been held by a contemporary, which the prophet‘s son would have been, than by one so much younger as the son of a younger brother; on the other hand the title “cohen” seems to point to a member of the royal family. (See the next note.) Azariah who was “over the officers” was chief, that is, of the “officers” mentioned in 1 Kings 4:8-19, as appears from the identity of the term here used with the title by which they are designated in 1 Kings 4:7.
Principal officer - Or, “cohen.” The fact that the title כהן kôhên was borne by sons of David 2 Samuel 8:18, who could not be “priests” in the ordinary sense of the word, seems to identify the Nathan of this verse with David‘s son 2 Samuel 5:14 rather than with the prophet.
