2 Chronicles 29:25-30

25And he set the Levites in the house of Jehovah with cymbals, with lutes, and with harps, according to the commandment of David, and of Gad the king's seer, and of Nathan the prophet; for the commandment was of Jehovah through his prophets.

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

27And Hezekiah commanded to offer up the burnt-offering on the altar. And at the moment the burnt-offering began, the song of Jehovah began, and the trumpets, accompanied by the instruments of David king of Israel.

28And all the congregation worshipped, and the singers sang, and the trumpeters sounded, all [the time] until the burnt-offering was finished.

29And when they had ended offering the burnt-offering, the king and all that were present with him bowed themselves and worshipped.

30And king Hezekiah and the princes commanded the Levites to sing praise to Jehovah with the words of David, and of Asaph the seer. And they sang praises with gladness, and bowed their heads and worshipped.
