'Work' in the Bible

if to the king it be good, let it be written to destroy them, and ten thousand talents of silver I weigh into the hands of those doing the work, to bring it in unto the treasuries of the king.'

And all heads of the provinces, and the lieutenants, and the governors, and those doing the work that the king hath, are lifting up the Jews, for a fear of Mordecai hath fallen upon them;

and all the work of his strength, and his might, and the explanation of the greatness of Mordecai with which the king made him great, are they not written on the book of the Chronicles of Media and Persia?
