Thematic Bible: The four living creatures

and before the throne there was as it were a sea of glass like to crystal; and in the middle before the throne, and around the throne, were four living creatures full of eyes before and behind. And the first living creature was like a lion, and the second living creature like a calf, and the third living creature had the face of a man, and the fourth living creature was like a flying eagle. And the four living creatures, having each of them six wings, around and within are full of eyes; and they have no rest day and night, saying, Holy, holy, holy, Lord God Almighty, who was, and who is, and who is to come.
