Ezekiel, Chapter One.
What Ezekiel saw was 4 living things (my text called them "cherubs") that looked like human beings, coming from a cloud. "They each had 4 faces and 2 pairs of wings. Their legs were straight like human legs but their feet were split like calves' feet and shone like bronze. The living beings could turn in the air."
The four faces that each being had were that of a man, a lion, an ox, and an eagle.
The four wings that each cherub had made a sound "like the noise of great waters, as the voice of the Almighty".
As Ezekiel looked beneath the beings he saw 4 wheels on the ground beneath them, one wheel belonging to each. "The rims of the 4 wheels were awesomely tall, and they were covered with eyes all around the edges. When the 4 living beings moved, the wheels moved with them. When they flew upward, the wheels went up too. When the living beings moved, the wheels moved. When they stopped the wheels stopped."
Each wheel had a smaller wheel inside of it
