Ezekiel 1:14-16

Amplified Bible

¹⁴ And the living beings moved rapidly back and forth like flashes of lightning.

¹⁵ Now as I looked at the living beings, I saw one wheel on the ground beside the living beings, for each of the four of them. ¹⁶ Regarding the appearance of the wheels and their construction: they gleamed like chrysolite (beryl, olivine); and the four were made alike. Their appearance and construction were a wheel [set at a right angle] within a wheel.
