Ezekiel 1:10-12

Their faces looked like this: In front a human face, on the right side the face of a lion, on the left the face of an ox, and in back the face of an eagle. So much for the faces. The wings were spread out with the tips of one pair touching the creature on either side; the other pair of wings covered its body. Each creature went straight ahead. Wherever the spirit went, they went. They didn’t turn as they went.
