Ezekiel 1:15-17
Ezekiel 1: 15 to 17
15 Now while I was looking at the four living beings, I saw one wheel on the earth, by the side of the living beings, for the four of them.
16 The form of the wheels and their work was like a beryl; the four of them had the same form and design, and they were like a wheel inside a wheel.
17 The four of them went straight forward without turning to one side.
