2 Chronicles 5:11-14

When the priests had come out of the holy place (for all the priests who were present had sanctified themselves, and didn’t keep their divisions; also the Levites who were the singers, all of them, even Asaph, Heman, Jeduthun, and their sons and their brothers, arrayed in fine linen, with cymbals and stringed instruments and harps, stood at the east end of the altar, and with them one hundred twenty priests sounding with trumpets); when the trumpeters and singers were as one, to make one sound to be heard in praising and thanking Yahweh; and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised Yahweh, saying, “For he is good, for his loving kindness endures forever!” then the house was filled with a cloud, even Yahweh’s house, so that the priests could not stand to minister by reason of the cloud; for Yahweh’s glory filled God’s house.
