Ezekiel 1:6

had four faces These were a man's in front of each, an eagle's opposite to this at the back of each; a lion's on the right hand of each, and the face of an ox on the left of each. Thus four different faces were presented in each direction, so that in whatever direction the whole moved, while a man's face was presented first, those of a lion, an ox and an eagle were also encountered. In this view the four living creatures made up one creature, and each of the four was in small that which the four were combined.
