a fellow official: one of the officers who hold a commission alongside the man named with them and act with him on government business
Every appearance of this word sits inside the imperial paperwork that the book of Ezra quotes: letters to and from the Persian court, and the reports of officers sent to see what the Jews were building in Jerusalem. The pattern is always the same. A man is named, his rank is given, and then his fellow officials are added as a block, with no names of their own. Rehum the commander and Shimshai the scribe write to King Artaxerxes together with theirs (Ezra 4:9), and Tattenai, the governor of the province west of the Euphrates, arrives with his to ask who authorized the temple (Ezra 5:3).
Three things hold true of the word every time it is used:
- it hangs on a named officer and never stands on its own
- it is always plural, naming a whole staff rather than a single partner
- it belongs to the language of official business, appearing only in letters, orders, and reports
That makes it a piece of government vocabulary rather than a word about friendship. The same phrasing, one man plus "his colleagues", runs through the surviving Aramaic paperwork of the Persian empire, where it marks a group of officers acting as one body. The men it names are not bystanders: they sign the letter that halts the building, they ride to Jerusalem and stop the work by force (Ezra 4:23), and later they carry out Darius's order to pay for the temple instead (Ezra 6:13).
Biblical Aramaic has a different word for a fellow (חֲבַר), used of Daniel's three friends, and it carries a warmth of companionship this one does not. The Hebrew verses of Ezra use the Hebrew form of this same word (כְּנָת) for the officials behind an earlier letter to the king (Ezra 4:7).
