'Service' in the Bible

The overseer of the Levites in Jerusalem was Uzzi son of Bani, the son of Hashabiah, the son of Mattaniah, the son of Mica. He was one of Asaph's descendants who were the singers responsible for the service of the temple of God.

They performed the service of their God and the service of purification, along with the singers and gatekeepers, according to the commandment of David and his son Solomon.
