Ezekiel 1:17-21

When they moved, they went toward any one of four directions; they did not turn aside when they went. As for their rims, they were so high they were awesome; and their rims were full of eyes, all around the four of them. When the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up. Wherever the spirit wanted to go, they went, because there the spirit went; and the wheels were lifted together with them, for the spirit of the living creatures was in the wheels. When those went, these went; when those stood, these stood; and when those were lifted up from the earth, the wheels were lifted up together with them, for the spirit of the living creatures was in the wheels.
