Ezekiel 10:3-5

Now the cherubim were standing on the south side of the house, when the man went in, and a cloud filled the inner court. And the glory of the LORD went up from the cherub to the threshold of the house, and the house was filled with the cloud, and the court was filled with the brightness of the glory of the LORD. And the sound of the wings of the cherubim was heard as far as the outer court, like the voice of God Almighty when he speaks.
