2 Chronicles 5:13-14

when 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 music, and praised the LORD, saying, “For he is good, for his loving kindness endures forever!” then the house was filled with a cloud, even the LORD’s house, so that the priests could not stand to minister by reason of the cloud; for the LORD’s glory filled God’s house.
