There aren't two Persons anywhere in Revelation. Duality of powers and not Persons! In Revelation the One sitting on the Throne was like Jasper and Sardis stones one precious stone is brilliant shine and the other is Red in colour. Which shows glory and the blood. These precious stones make up the last and first stone the High Priest wore in OT. Cryptic language has to be understood. He and the Lamb aren't two Persons for it's by His blood He has redeemed and made us kings and priests:
Rev 4:
4 Around the throne were twenty-four thrones. On the thrones were twenty-four elders sitting, dressed in white garments, with crowns of gold on their heads.
Why are there 24 elders? It's both (12 tribes + 12 Apostles) OT and NT combined just like the 2 witnesses of Rev 11 standing for The Law and The Prophets. They testify to the Spirit of Christ (represented by the 7 horns and 7 eyes of the Lamb). YHWH and The Lamb are one the same in duality of powers and not in Persons - The First Who is also The Last.
Dan 7:9
“I watched until thrones were placed, and
one who was ancient of days sat. His clothing was white as snow, and the hair of his head like pure wool. His throne was fiery flames, and its wheels burning fire.
Compare this with Rev 1:
14 His head and his hair were white as white wool, like snow. His eyes were like a flame of fire.
Compare with also:
Ezk 1:
26 Above the expanse that was over their heads was the
likeness of a throne, as the appearance of a sapphire note stone. On the likeness of the throne was a likeness as the appearance of a man on it above.
27 I saw as it were glowing metal, as the appearance of fire within it all around,
from the appearance of his waist and upward; and from the appearance of his waist and downward I saw as it were the appearance of fire, and there was brightness around him.
28 As the appearance of the rainbow that is in the cloud in the day of rain, so was the appearance of the brightness all around. This was the appearance of the likeness of the LORD’s glory. When I saw it, I fell on my face, and I heard a voice of one that spoke.
Every scripture points to Christ. He is the revelation of Himself as the unapproachable and invisible God.
