2 Chronicles 5:13-14

And they sounded the trumpets and sang with one voice, all together as one man praising and thanking the LORD, when they lifted up their voice with trumpets and cymbals and instruments of music, when they praised the LORD, saying, For he is good, for his mercy endures for ever; and the house was filled with a cloud, even the house of the LORD, so that the priests could not stand to minister by reason of the cloud, for the glory of the LORD had filled the house of God.
