'Seven Spirits of God' in the Bible

And to the messenger of the church in Sardis write: Thus says he having the seven spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead:

And from the throne go forth lightnings, and thunders, and voices: and seven torches of fire burning before the throne, which are the seven Spirits of God.

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