Revelation 5:5-6

5Then one of the leaders said to me, ‘Do not weep! Look! There is someone who can break the seven seals and then open the book. His name is the Lion from Judah's tribe. He is called the Root of King David. He has won over all his enemies.’

6Then I saw a Lamb. He was standing in the middle of the throne. The four beings that are alive and the leaders were around him. The Lamb appeared to be like a lamb that someone had killed. He had seven horns and seven eyes. His eyes are the seven spirits of God, that God has sent into all parts of the world.
