Revelation 5:5-6

5Then one of the elders tells me, “Stop weeping! Behold, the Lion of the tribe of Judah, the Root of David, has triumphed—He is worthy to open the scroll and its seven seals.”

6And in the midst of the throne and the four living creatures, and in the midst of the elders, I saw a Lamb standing, as having been slain—having seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.
