Ezekiel 10:9-11

Amplified Bible

⁹ Then I looked and behold, [there were] four wheels beside the cherubim, one wheel beside one cherub and another wheel beside each other cherub; and the appearance of the wheels was like a sparkling Tarshish stone (beryl). ¹⁰ As for their appearance, all four looked alike, as if one wheel were within another wheel. ¹¹ When they moved, they went in any of their four directions without turning as they went; but they followed in the direction which they faced, without turning as they went.
