Revelation 4:6-9

6and before the throne, as a glass sea, like crystal. And in the midst of the throne, and around the throne, four living creatures, full of eyes, before and behind;

7and the first living creature like a lion, and the second living creature like a calf, and the third living creature having the face as of a man, and the fourth living creature like a flying eagle.

8And the four living creatures, each one of them having respectively six wings; round and within they are full of eyes; and they cease not day and night saying, Holy, holy, holy, Lord 1God Almighty, who was, and who is, and who is to come.

9And when the living creatures shall give glory and honour and thanksgiving to him that sits upon the throne, who lives to the ages of ages,
