“And I saw in the right hand of Him who sat on the throne a scroll written inside and on the back, sealed with seven seals. Then I saw a strong angel proclaiming with a loud voice, ‘Who is worthy to open the scroll and to loose its seals?’ And no one in heaven or on the earth or under the earth was able to open the scroll, or to look at it. So I wept much, because no one was found worthy to open and read the scroll, or to look at it.” Revelation 5:1-4.
“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 creatures full of eyes in front and in back. The first living creature was like a lion, the second living creature like a calf, the third living creature had a face like a man, and the fourth living creature was like a flying eagle. “And the four living creatures, each having six wings, were full of eyes around and within. And they do not rest day or night, saying: ‘Holy, holy, holy, Lord God Almighty, Who was and is and is to come!’” Revelation 4:6-8.
