The appearance of the wheels and their work [was] like unto the colour of a beryl: and they four had one likeness: and their appearance and their work [was] as it were a wheel in the middle of a wheel.
Berean Study Bible (BSB) - Ezekiel 1:16 >The workmanship of the wheels looked like the gleam of beryl, and all four had the same likeness. Their workmanship looked like a wheel within a wheel.
