'Serving' in the Bible

These are those serving the king, apart from those whom the king put in the cities of fortress, in all Judah.

And at their completing it, they have brought in before the king and Jehoiada the rest of the money, and they make it vessels for the house of Jehovah, vessels of serving, and of offering up, and spoons, even vessels of gold and silver; and they are causing burnt-offerings to ascend in the house of Jehovah continually, all the days of Jehoiada.
