6 And before the throne there was a sea of glass like crystal: And in the midst of the throne, and around the throne, were four living beings full of eyes before and behind.
7 And the first living being was like a lion, and the second living being like a calf, and the third living being had a face as a man, and the fourth living being was like a flying eagle.
8 And the four living beings had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, who was, and is, and is to come.
