Ezekiel 1:24; Ezekiel 10:5

24 And when they went , I heard the noise of their wings, like the noise of great waters, as the voice of the Almighty, the voice of speech, as the noise of an host: when they stood , they let down their wings.
5 And the sound of the cherubims' wings was heard even to the outer court, as the voice of the Almighty God when he speaketh .
