2 Chronicles 29:25-29

He then stationed the Levites in the house of the Lord with cymbals, harps, and lyres, according to the command of David and of Gad, the king’s seer, and of Nathan the prophet; for the command was from the Lord through His prophets.

The Levites stood with the musical instruments of David, and the priests with the trumpets.

Then Hezekiah gave the order to offer the burnt offering on the altar. When the burnt offering began, the song to the Lord also began with the trumpets, accompanied by the instruments of David, king of Israel.

While the whole assembly worshiped, the singers also sang and the trumpets sounded; all this continued until the burnt offering was finished.

Now at the completion of the burnt offerings, the king and all who were present with him bowed down and worshiped.
