Ezekiel 10:7-11

And one cherub stretched forth his hand from between the cherubims unto the fire that was between the cherubims, and took thereof, and put it into the hands of him that was clothed with linen: who took it, and went out.

And there appeared in the cherubims the form of a man’s hand under their wings.

And when I looked, behold the four wheels by the cherubims, one wheel by one cherub, and another wheel by another cherub: and the appearance of the wheels was as the colour of a beryl stone.

And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel.

When they went, they went upon their four sides; they turned not as they went, but to the place whither the head looked they followed it; they turned not as they went.
