And there was an ocean, as crystal-clear as glass, in front of the throne. And at the center, surrounding the throne were four living beings, covered with eyes in the front and back of them. [Note: In view of Isa. 6:1-3 and especially Eze. 10:20ff, these "living beings" appear to be some special order of heavenly beings who inhabit the presence of God].

Then I saw a Lamb, looking like it had been killed. He was standing in the center of the throne, surrounded by the four living beings and the [twenty-four] elders. He has seven horns and seven eyes, which are the seven Spirits of God [i.e., the Holy Spirit. See 1:4], sent throughout the entire earth.

For the Lamb, who is at the center of the throne, will be their Shepherd and will lead them to springs of living water. And God will wipe away every tear from their eyes."
