Diḇre haYamim Bĕt (2 Chronicles) 5:13-14

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.
