Ezekiel 1:6

And every one had four faces: the first face was the face of a cherub, and the second face was the face of a man, and the third the face of a lion, and the fourth the face of an eagle.

And the cherubims shall stretch forth their wings on high, covering the mercy seat with their wings, and their faces shall look one to another; toward the mercy seat shall the faces of the cherubims be.

Now as I beheld the living creatures, behold one wheel upon the earth by the living creatures, with his four faces.

And as for their appearances, they four had one likeness, as if a wheel had been in the midst of a wheel.

Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
