Charles Ellicott Commentary Ezekiel 1:10

"As for the likeness of their faces, they had the face of a man; and they four had the face of a lion on the right side; and they four had the face of an ox on the left side; they four had also the face of an eagle." — Ezekiel 1:10 (ASV)

On the right side ... on the left side. — The apparent obscurity of this description is due only to the punctuation in the English Bible. They four had the face of a man (namely, in front, as Ezekiel viewed them), and the face of a lion on the right side; and they four had the face of an ox on the left side; they four also had the face of an eagle (namely, on the back, or side opposite to Ezekiel). These faces are the same as those given to the living creatures in Revelation 4:7, except that there each creature had but one of them.
