Revelation 5:5-6

5Then 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.”

6Then 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.
