2 Chronicles 29:25-28

25And he stationed the Levites in the house of the Lord with cymbals, with stringed instruments, and with harps, according to the commandment of David, of Gad the king’s seer, and of Nathan the prophet; for thus was the commandment of the Lord by His prophets.

26The Levites stood with the instruments of David, and the priests with the trumpets.

27Then Hezekiah commanded them to offer the burnt offering on the altar. And when the burnt offering began, the song of the Lord also began, with the trumpets and with the instruments of David king of Israel.

28So all the assembly worshiped, the singers sang, and the trumpeters sounded; all this continued until the burnt offering was finished.
