'Wheelwork' in the Bible

The Lord said to the man dressed in linen, "Go between the wheelwork underneath the cherubim. Fill your hands with burning coals from among the cherubim and scatter them over the city." He went as I watched.

When the Lord commanded the man dressed in linen, "Take fire from within the wheelwork, from among the cherubim," the man went in and stood by one of the wheels.

As for their wheels, they were called "the wheelwork" as I listened.
