Ezekiel 10:9-10

King James Version

⁹ 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.

¹⁰ And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel.
