'Whirling' in the Bible

The LORD spoke to the man who was clothed in white linen, telling him, "Go between the whirling wheels, under the cherubim, and fill your hands with burning coals from among the cherubim. Then scatter them over the city." So he entered as I watched.

He issued this order to the man who was clothed in white linen: "Take fire from within the whirling wheels, among the cherubim." So he went and stood beside the wheels.

The wheels whose sound I was hearing were called "the whirling wheels".
