Revelation 4:5

And out of the throne proceed lightnings and voices and thunders. And there were seven lamps of fire burning before the throne, which are the seven Spirits of God;

Thunder and lightning, etc. ... "These announce the presence of God, as at Sinai (Exodus 19:16), and the seven burning lamps refer to the Holy Spirit."[36] The combined symbols of this verse convey no meaning except that of "God's omnipotent power."[37] Subsequent versions use "torches" here instead of lamps, and perhaps that is better. Carpenter found a suggestion in this of the "torch" that moved between the parted sacrifice in the account of the Abrahamic covenant (Genesis 15:17), indicating that both of God's covenants with Noah and with Abraham were symbolized in this chapter.
