'Service of God' in the Bible

For their office was to wait on the sons of Aaron for the service of the house of the LORD, in the courts, and in the rooms, and in the purifying of all holy things, even the work of the service of God's house;

All these were under the hands of their father for song in the house of the LORD, with cymbals, stringed instruments, and harps, for the service of God's house; Asaph, Jeduthun, and Heman being under the order of the king.

Behold, there are the divisions of the priests and the Levites, for all the service of God's house. There shall be with you in all kinds of work every willing man who has skill, for any kind of service. Also the captains and all the people will be entirely at your command."

and they gave for the service of God's house of gold five thousand talents and ten thousand darics, and of silver ten thousand talents, and of brass eighteen thousand talents, and of iron a hundred thousand talents.
