4 Ezra 11:37
2 Esdras36 Then I heard a voice which said to me: ‘Look carefully at what you see before you.’ 37 I looked, and saw what seemed to be a lion roused from the forest; it roared as it came, and I heard it address the eagle in a human voice. 38 ‘Listen to what I tell you’, it said. 39 ‘The Most High says to you: Are you not the only survivor of the four beasts to which I gave the rule over my world, intending through them to bring my ages to their end?
Revelation 5:5
3 But no one in heaven or on earth or under the earth was able to open the scroll or look into it. 4 So I began weeping bitterly because no one was found who was worthy to open the scroll or to look into it. 5 Then one of the elders said to me, “Stop weeping! Look, the Lion of the tribe of Judah, the root of David, has conquered; thus he can open the scroll and its seven seals.” 6 Then I saw standing in the middle of the throne and of the four living creatures, and in the middle of the elders, a Lamb that appeared to have been killed. He had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.
Notes and References
"... No one is found and John weeps bitterly (Revelation 5:4). Then he is told to weep no more because one has indeed been found. The drama here underscores the utter uniqueness of the one who is found. It is as if the entire universe has been scoured, and only one is found. Only one can open the scroll. The angel tells John, in effect, that a king, great and powerful enough to break open the scroll has made an appearance. It is “the Lion of the tribe of Judah, the Root of David,” a great conqueror who can open the scroll. “The Lion of the tribe of Judah” alludes to one of the first messianic prophecies in the Bible, Genesis 49:9-10. We know from other Jewish literature of New Testament times that the lion was used to indicate the conquering Messiah (e.g., see 4 Ezra 11:37; 12:31]), even though the metaphor is not found elsewhere in the New Testament ..."
