Diḇre haYamim Bĕt (2 Chronicles) 5:11-14

And it came to be when the priests came out of the Most Set-apart Place – for all the priests who were present had set themselves apart, there was none to watch by division – and the Lĕwite singers, all those of Asaph and Hĕman and Yeḏuthun, with their sons and their brothers, stood at the east end of the slaughter-place, dressed in white linen, having cymbals and harps and lyres, and with them one hundred and twenty priests sounding with trumpets. Then it came to be, as the trumpeters and singers were as one, to make one sound to be heard in praising and thanking יהוה, and when they lifted up their voice with the trumpets, and with cymbals, and with instruments of song, and giving praise to יהוה, “For He is good, for His loving-commitment is everlasting,” that the house, the House of יהוה, was filled with a cloud, and the priests were unable to stand and perform the service because of the cloud, for the esteem of יהוה filled the House of Elohim.
