2 Chronicles 29:25-26

25The king told the Levites to stand in the Lord's temple with their cymbals, harps and lyres to make music. They stood at the places where King David, David's prophet Gad and the prophet Nathan had told the Levites to stand. This was the Lord's command that he had given to his prophets.

26The Levites held the musical instruments that King David had provided. The priests held their trumpets.
