In Context

11 And it came to pass, when the priests had come out of the holy place: (for all the priests that were present were sanctified, and did not then wait by course:

12 Also the Levites who were the singers, all of them of Asaph, of Heman, of Jeduthun, with their sons and their brethren; being arrayed in white linen, having cymbals and psalteries and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets:)

13 It came even to pass, as the trumpeters and singers were as one, to make one sound to be heard in praising and thanking the LORD; and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised the LORD, saying, For he is good; for his mercy endureth for ever: that then the house was filled with a cloud, even the house of the LORD;

14 So that the priests could not stand to minister by reason of the cloud: for the glory of the LORD had filled the house of God.
