Ezekiel 10:9

I looked, and behold, there were four wheels beside the cherubim, one wheel beside one cherub, and another wheel beside another cherub. The appearance of the wheels was like a beryl stone.

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.
