'Work' in the Bible

All the officials of the provinces, the satraps, governors, and {those who did the work of the king} [were] supporting the Jews, because the fear of Mordecai had fallen on them.

All the work of his authority and his {powerful deeds}, and the full accounting of the greatness of Mordecai, to which the king advanced him, are they not written on the scroll of the {chronicles} of the kings of Media and Persia?
