In Context

11 And it came to pass, when the priests were come out of the holy place, (for all the priests that were present had sanctified themselves, and did not keep their courses;

12 also the Levites which were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brethren, arrayed in fine linen, with cymbals and psalteries and harps, stood at the east end of the altar, and with them an hundred and twenty priests sounding with trumpets:)

13 it came even to pass, when 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 filled the house of God.
