2 Chronicles 5:13-14

13it came to pass, when the trumpeters and singers were as one, to make one sound to be heard in praising and thanking Jehovah; and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised Jehovah, saying, For he is good; for his lovingkindness endureth for ever; that then the house was filled with a cloud, even the house of Jehovah, 14so that the priests could not stand to minister by reason of the cloud: for the glory of Jehovah filled the house of God.
