2 Chronicles 5:14

11 And it came to pass, when the priests were 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 [which 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 an 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 musick, 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.
