2 Chronicles 29:28-30

28All the people there were worshipping the Lord. At the same time the singers were singing and the priests were making music with their trumpets. They all continued to do that until the priests finished making the burnt offering.

29When the priests finished offering the sacrifices, the king and everyone with him bent down low to worship God.

30King Hezekiah and his officers told the Levites to sing songs to praise the Lord. They told them to sing the songs that King David and the prophet Asaph had written. So the Levites praised God in that way. They were very happy and they bent down low to worship God.
