Revelation 4:6-8 Amplified Bible, Classic Edition (AMPC)

⁶ And in front of the throne there was also what looked like a transparent glassy sea, as if of crystal. And around the throne, in the center at each side of the throne, were four living creatures (beings) who were full of eyes in front and behind [with intelligence as to what is before and at the rear of them].

⁷ The first living creature (being) was like a lion, the second living creature like an ox, the third living creature had the face of a man, and the fourth living creature [was] like a flying eagle.

⁸ And the four living creatures, individually having six wings, were full of eyes all over and within [underneath their wings]; and day and night they never stop saying, Holy, holy, holy is the Lord God Almighty (Omnipotent), Who was and Who is and Who is to come.
