2 Chronicles 29:25-28

25And he set the Levites in the house of Yhwh with cymbals, with psalteries, and with harps, according to the commandment of David, and of Gad the king’s seer, and Nathan the prophet: for so was the commandment of Yhwh by his prophets.12

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

27And Hezekiah commanded to offer the burnt offering upon the altar. And when the burnt offering began, the song of Yhwh began also with the trumpets, and with the instruments ordained by David king of Israel.34

28And all the congregation worshipped, and the singers sang, and the trumpeters sounded: and all this continued until the burnt offering was finished.5
