Ezekiel 1:16-18

1:16 The appearance of the wheels and their construction was like gleaming jasper, and all four wheels looked alike. Their structure was like a wheel within a wheel. 1:17 When they moved they would go in any of the four directions they faced without turning as they moved. 1:18 Their rims were high and awesome, and the rims of all four wheels were full of eyes all around.
