2 Chronicles 5:13-14

it happened, when the trumpet players and singers made one sound to praise and give thanks to the LORD, and when they lifted up their voice with the trumpets and cymbals and all the instruments of music and praised the LORD saying, “For He is good and His mercy endures forever,” that the house, the house of the LORD, was filled with a cloud. And the priests were not able to stand in order to serve because of the cloud, for the glory of the LORD had filled the house of God.
