'Business' in the Bible

If it please the king, let it be written that they be destroyed: and I will pay ten thousand talents of silver into the hands of those that have the charge of the king's business, to bring it into the king's treasuries.

And all the princes of the provinces, and the satraps, and the governors, and they that did the king's business, helped the Jews; because the fear of Mordecai was fallen upon them.
