Now viewing scripture range from the book of Ezekiel chapter 1:16 through chapter 1:19...
16 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.
17 When they went, they went upon their four sides: and they turned not when they went.
18 As for their rings, they were so high that they were dreadful; and their rings were full of eyes round about them four.
19 And when the living creatures went, the wheels went by them: and when the living creatures were lifted up from the earth, the wheels were lifted up.
