REV 4:7

7 The first living [creature] was like a lion. The second living [creature] was like an ox. The third living [creature] had a face like a man’s face. The fourth living creature was like an eagle that was flying. Each of the four living [creatures] had six wings. They were covered with eyes, all around [their bodies] and under [their wings]. Day and night they continually [LIT] sing: Holy, holy, holy is the Lord God, the Almighty One. He is the one who has always existed, who exists now, and who will always exist.
