'Seven Spirits of God' in the Bible

“Write to the angel of the church in Sardis:“The One who has the seven spirits of God and the seven stars says: I know your works; you have a reputation for being alive, but you are dead.

Flashes of lightning and rumblings of thunder came from the throne. Seven fiery torches were burning before the throne, which are the seven spirits of God.

Then I saw One like a slaughtered lamb standing between the throne and the four living creatures and among the elders. He had seven horns and seven eyes, which are the seven spirits of God sent into all the earth.
