Ezekiel 10:5

I also heard the sound of their wings like the sound of many waters as they went, like the sound of the Almighty, a sound of tumult like the sound of an army camp; whenever they stood still, they dropped their wings.

Then he brought me into the outer court, and behold, there were chambers and a pavement made for the court all around; thirty chambers faced the pavement.
