2 Chronicles 5:12-14

12and the Levites the singers, all they of Asaph, of Heman, of Jeduthun, with their sons and their brethren, clad in byssus, with cymbals and lutes and harps, stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets), 13— it came to pass when the trumpeters and singers were as one, to make one voice to be heard in praising and thanking Jehovah; and when they lifted up their voice with trumpets, and cymbals, and instruments of music, and praised Jehovah: For he is good, for his loving-kindness [endureth] for ever; that then the house, the house of Jehovah, was filled with a cloud, 14and the priests could not stand to do their service because of the cloud; for the glory of Jehovah had filled the house of 1God.
