Revelation 1:4
(Written by God through the Apostle) John, to the seven (select) churches that are in Asia- (greetings) grace and peace to you- from Him who is and who was and who is to come, and from the Seven Spirits who are before His throne.

There is revelation of the Seven Spirits of God in some scrolls of Revelation:

It appears that this symbolic revelation of God the Holy Spirit is revealed in Revelation Scroll Number One-
John, to the seven churches that are in Asia- Grace to you and peace from Him who is and who was and who is to come, and from the seven Spirits who are before His throne
(Revelation 1:4).

This symbolism is also revealed in Revelation Scroll Number Six-
And to the angel of the church in Sardis write-
He who has the seven spirits of God, and the seven stars says these things- I know your works, that you have a reputation of being alive, but you are dead
(Revelation 3:1).

And this symbolism is revealed in Revelation Scroll Number Nine-
...Seven burning lamps of fire were before the throne that are the seven Spirits of God
(Revelation 4:5).

And I looked, and behold, in the middle of the throne and of the four Living Beings, and in the middle of the elders, stood a Lamb as though it had been slain, having seven horns and seven eyes, that are the seven Spirits of God sent out into all the earth
(Revelation 5:6).

God the Holy Spirit is also symbolically associated with fire:
Are there other scrolls in the bible that appear to reveal this? Yes. Here are a few-

I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire
(Matthew 3:11).

And the Lord went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night
(Exodus 13:21). He spread a cloud for a covering, and fire to give light in the night
(Psalm 105:39).

Their buds and their branches were of one piece with it. The whole thing was one beaten work of pure gold. He made its seven (burning) lamps...of pure gold
(Exodus 37:22-23).

So Elijah answered and said to the captain of fifty- if I am a man of God, then let fire come down from heaven and consume you and your fifty men. And fire came down from Heaven and consumed him and his fifty
(2 Kings 1:10).

Let your loins be girded about, and your lamps burning
(Luke 12:35).

God the Holy Spirit reveals this about Himself:
You shall make seven lamps for it, and they shall arrange its lamps so that they give light in front of it. And its wick-trimmers and their trays shall be of pure gold. It shall be made of a talent of pure gold, with all these utensils. And see to it that you make them according to the pattern that was shown you on the mountain
(Exodus 25:37-40).

Speak to Aaron, and tell him- when you light the lamps, the seven lamps shall give light in front of the lamp stand
(Numbers 8:2).

It will happen at that time, that I will search Jerusalem with lamps...
(Zephaniah).

...these seven lamps represent the eyes of the Lord that search all around the world
(Zechariah 4:10).

When Aaron lights the lamps at evening- he shall burn it a perpetual incense before Yahweh throughout your generations
(Exodus 30:8).

Let us take a look at a few more scriptures that reveal God the Holy Spirit-

The Prophet, Isaiah, under inspiration, had this to say about God the Holy Spirit-
...and the Spirit of the Lord shall rest upon Him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord
(Isaiah 11:2).

The Apostle John, under inspiration, penned the words of Jesus in regards to God the Holy Spirit-
...if you love Me, you will obey Me. And I will ask the Father, and He will give you another Comforter to be with you forever- the Spirit of truth. The evil world system cannot receive Him because it does not see Him or recognize Him. But you recognize Him because He lives with you and will be in you
(John 14:15-17). But the Comforter, the Holy Spirit whom the Father will send at My request, will teach you (all relevant spiritual) things, and He will bring to your recall all that I have taught you (everything that is pertinent)
(John 14:26). But when the Comforter has come, Whom I will send unto you from the Father, even the Spirit of Truth, Who procees from the Father, He shall testify of Me
(John 15:26)...when...the Spirit of Truth, has come, He will guide you into all truth, for He will not speak His own agenda (message) but whatever comes from the throne is what He will say, and He will declare to you (some) things to come. He will give Me glory, because He will take of what is Mine, and declare it to you. Everything that the Father has is Mine- that is why I say, He will take of what is Mine and will declare it to you
(John 16:13-15).

The expression "the seven Spirits that are before His throne" can also mean "the Seven Spirits in the presence of His throne". Why is God the Holy Spirit referred to that way? The Greek word for "spirits" is Pneuma, and in this context it refers to God the Holy Spirit. Let us further look at some of the symbolism for God the Holy Spirit as found in other biblical scrolls-
And there shall come forth a plant shoot out of the tree trunk of Jesse, and a Branch out of his roots shall be fruitful- and the spirit of the Lord shall rest on Him-
(1) the spirit of wisdom and
(2) understanding,
(3) the spirit of counsel and
(4) might (power),
(5) the spirit of knowledge and of the fear of the Lord, and
(6) righteousness will be the cord of his robe, and
(7) faithfulness will be the band round his breast
(Isaiah 11:1-5).
So, this scripture above appears to be a partial description of Him. Jesus said-
...the Spirit of truth...will guide you into all the truth, for He will not speak from Himself, but whatever things He hears, He will speak. He will declare to you the things that are to come
(John 16:13).

It is revealed in Revelation Scroll Number Nine-
She (Israel) bore a male Child who was to rule all nations with a rod of iron. And her Child was caught up to God and His throne
(Revelation 12:5).

And it is revealed in Revelation Scroll Number Twelve-
And he showed me a pure river of water of life, clear as crystal, proceeding from the throne of God and of the Lamb (Revelation 22:1)...and there shall be no more curse, but the throne of God and of the Lamb shall be in it, and His servants shall serve Him
(Revelation 22:3).

Are there other scrolls in the bible that appear to reveal this? I think so:

Christ mentioned His throne-
So Jesus said to them- assuredly I say to you, that in the regeneration, when the Son of Man sits on the throne of His glory, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel
(Matthew 19:28).

Each royal Overcomer will live and reign with Christ. Royalty reveals a sharing of Christ's throne (Revelation 3:21).
Christ...has made us kings...to His God and Father...
(Revelation 1:5-6).

As well, each Overcomer will share Christ's throne and have the authority of a royal judge-
Do you not know that the saints will judge the world? (1 Corinthians 6:2).

And I bestow upon you a kingdom, just as My Father bestowed one upon Me (Luke 22:29).

It appears that God the Father, God the Son, and God the Holy Spirit share a throne in Heaven:

This is revealed in Revelation Scroll Number One-
John, to the seven churches that are in Asia...from the Seven Spirits Who are in the presence of the same throne
(Revelation 1:4).

and it is revealed in Revelation Scroll Number Nine-
And from the throne proceeded lightnings, thunderings, and voices. Seven Lamps of Fire were burning in the presence of the throne that are the Seven Spirits of God
(Revelation 4:5).

And I looked, and behold, in the middle of the throne and of the four Living Beings, and in the midle of the elders, stood a Lamb as though it had been slain, having seven horns and seven eyes, that are the Seven Spirits of God sent out into all the earth
(Revelation 5:6).

Is there another scroll in the bible that also appears to reveal this? I think so-

God's Unity
I and My Father are one (John 10:30)...and the glory that You gave Me I have given them- that they may be one just as We are one
(John 17:22).

Revelation 1:5
and from Jesus Christ, the faithful witness, the firstborn from the dead, and the ruler over the kings of the earth. To Him who loved us and washed us from our sins in His own blood.

God the Father and God the Holy Spirit have already said "hello" to you, so now, Jesus says "hello" to you also.

This scripture speaks of the eternal existence of Jesus Christ because He is God the Son. Jesus repeats this truth about Himself in verse eight.

You have just been greeted by the three Persons in the Holy Trinity. These three are one and are the most important, holy, and powerful in all of creation.

Are there other scrolls in the bible that appear to reveal this? Yes-

So they said to Jeremiah- let the Lord be a true and faithful witness between us...
(Jeremiah 42:5).

There is another who bears witness of Me, and I know that the witness that He witnesses of Me is true (John 5:32)...but I have a greater witness than John's- for the works that the Father has given Me to finish- the very works that I do- bear witness of Me, that the Father has sent Me
(John 5:36).

Jesus answered and said to them- even if I bear witness of Myself, My witness is true
(John 8:14)...I AM One who bears witness of Myself, and the Father who sent Me bears witness of Me
(John 8:18).

Jesus answered them- I told you, and you do not believe. The works that I do in My Father's name, they bear witness of Me. But you do not believe, because you are not of My sheep, as I said to you
(John 10:25-26).

...I AM a king. For this cause I was born, and for this cause I have come into the world, that I should bear witness to the truth. Everyone who is of the truth hears My voice
(John 18:37).

So all bore witness to Him, and marveled at the gracious words that proceeded out of His mouth

(1 Timothy 6:13).

Now out of His mouth goes a sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron...
(Revelation 19:15).

So, what are some possible select biblical scriptures for the above verses in Revelation?

Ask of Me, and I will give You the nations for Your inheritance, and the ends of the earth for Your possession. You shall break them with a rod of iron- You shall dash them to pieces like a potter's vessel
(Psalm 2:8-9).

But to the Son He says- Your throne, O God, is forever and ever- a scepter of righteousness is the rod of Your Kingdom

His seed shall endure forever, and His throne as the sun before Me- it shall be established forever like the moon- even like the faithful witness in the sky- Selah
(Psalm 89:36-37).
