'Seven Spirits of God' in the Bible

And unto the angel of the church in Sardis, write, "THESE things saith he that hath the seven spirits of God and the seven stars; I know thy works, that thou hast the reputation of being alive, but art dead.

out of the throne proceeded lightnings, and thundrings, and voices: and there were seven lamps of fire burning before the throne, which are the seven spirits of God.

And I beheld, and saw before the throne, in the midst of the four animals, and in the midst of the elders, a lamb which seem'd to have been slain, having seven horns, and seven eyes, which are the seven spirits of God sent forth into all the earth.
