scholars assumed on their own that Apollyon is Satan = the Scriptures deny that assumption
Thus why John said: "in Hebrew Abaddon"
Abaddon is
the place of the dead = OT
Sheol and
Abaddon lie open before the LORD; how much more the hearts of the children of man!
Whereas Satan roams the earth = Job 1:6-7
One day the sons of God came to present themselves before the LORD, and Satan also came with them.
“Where have you come from?” said the LORD to Satan.
“From roaming through the earth,” he replied, “and walking back and forth in it.”
Satan continues roaming the earth and will do so until the 2nd Coming of Christ = 1 Peter 5:8
Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.
Satan also rules from above the earth = Ephesians 2:2
You used to live in sin, just like the rest of the world, obeying the devil—the commander of the powers in the unseen world.
He is the spirit at work in the hearts of those who refuse to obey God.
Satan has yet to be cast out of the heavens = Revelation 12:7-9
Then a war broke out in heaven: Michael and his angels fought against the dragon, and the dragon and his angels fought back.
But the dragon was not strong enough, and no longer was any place found in heaven for him and his angels.
And the great dragon was hurled down—that ancient serpent called the devil and Satan, the deceiver of the whole world. He was hurled to the earth, and his angels with him.
Satan has NEVER been locked up in the Abyss - but - will only go be sent there at the 2nd Coming of Christ = Rev 20:1-3
Then I saw an angel coming down from heaven with the key to the Abyss, holding in his hand a great chain.
He seized the dragon, that ancient serpent who is the devil and Satan, and bound him for a thousand years. And he threw him into the Abyss, shut it, and sealed it over him, so that he could not deceive the nations until the thousand years were complete.
After that, he must be released for a brief period of time.
