When the creatures moved, I heard the sound of their wings like the roar of many waters, like the voice of the Almighty, like the tumult of an army. When they stood still, they lowered their wings.
KJV
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.
ASV
And when they went, I heard the noise of their wings like the noise of great waters, like the voice of the Almighty, a noise of tumult like the noise of a host: when they stood, they let down their wings.
