'Cloud' in the Bible

it happened, 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!" that then the house was filled with a cloud, even the house of Yahweh,

so that the priests could not stand to minister by reason of the cloud: for the glory of Yahweh filled the house of God.
