'Service of God' in the Bible

For their duty is to assist [the priests] the sons of Aaron in the service of the house of the Lord, in [caring for] the courtyards, the chambers, the purifying of all holy things, and any work of the service of the house of God,

All these men were under their own fathers’ authority for the music in the Lord’s temple, with cymbals, harps, and lyres for the service of God’s temple. Asaph, Jeduthun, and Heman were under the king’s authority.

And see, [you have] the divisions of the priests and Levites for all the service of God’s house, and every willing, skillful man will be with you in all the kinds of work for any kind of service. Also the officers and all the people will be entirely at your command.”

For the service of God’s house they gave 185 tons of gold and 10,000 gold coins, 375 tons of silver, 675 tons of bronze, and 4,000 tons of iron.
