'Ministry' in the Bible

And the priests waited on their offices: the Levites also with instruments of musick of the LORD, which David the king had made to praise the LORD, because his mercy endureth for ever, when David praised by their ministry; and the priests sounded trumpets before them, and all Israel stood.

Following proscriptions laid down by his father David, Solomon appointed divisions of priests for their service as well as descendants of Levi for duties of praise and ministry before the priests consistent with the daily rules. Furthermore, because David, the man of God, had commanded it, Solomon also appointed gatekeepers to serve by divisions at every gate of the Temple.

When they finished, they presented the rest of the money to the king and Jehoiada, who made articles for the Lord’s temple with it—articles for ministry and for making burnt offerings, and ladles and articles of gold and silver. They regularly offered burnt offerings in the Lord’s temple throughout Jehoiada’s life.

Hezekiah reestablished the divisions of the priests and Levites for the burnt offerings and fellowship offerings, for ministry, for giving thanks, and for praise in the gates of the camp of the Lord, each division corresponding to his service among the priests and Levites.
