I see, I have to further clarify what I have warned of the misinterpretation of 2 Peter 2:4 and Jude 1:6.
Where a common myth suggests that the fallen angels are in prison and waiting for destruction on the final day, rather that teaching originates from the fear of a mind that has fallen from the grace of God (1 Timothy 4:1, Matthew 8:29, 2 Samuel 14:14).
The specific errors in that myth rely upon the twisting of scripture (as all false doctrine does), so that the one who is reading in error is blinded by their belief, unable to see the full and proper meaning of the original words.
In this case, there is two instances of that happening:
"imprisoned" is being put in place of the word "chained/restrained/pits" and "final judgement" is being put in place of the expression "judgement of the great day". Although these seem trivial, it is the meaning behind the words and the way in which they are used, that gives advantage to the spirits that vie for dominance in the reader's mind.
So I am bringing to light that there is a widespread culture that twists these scriptures to convey a meaning that is different from what The Holy Spirit conveys through the original writer, and while the English language is adding complication to the reader, 2 Peter 3:16 shows that the problem is essentially spiritual - that is to say that even two people who speak the same language can be disunited where they are "speaking past each other" as it were (ie: "confirmation bias"). Consider 1 John 4:6 and James 4:1-2.
When we speak of the angels who have not kept their proper place, we are speaking of those who have been tempted to take advantage of their position of power, to subdue the human and make something for themselves from him (an offspring, idolaters) - having disregarded God's intention and purpose for them (Hebrews 1:13-14, Hebrews 2:16), and by so opposing Him, have become satanic. The consequence of sin, as we see in Adam and Eve's case, is that they are convicted in God's presence, unable to approach Him (eg: 1 Timothy 6:16, Psalms 24:3-4) because their conscience testifies against them, that that the life lost as a result of their rebellion is on their very own hands. They cannot escape that conviction as long as the consequences are evident (Romans 8:22). They are unable to escape darkness/gloominess, bound tight by unbreakable chains and being cut off from God so that they wander in gloominess, darkness and fear - and yet, they remain of their given form, able to do their duty as designed, but confused just as Adam and Eve were, about God's true nature. This, they have verified by putting Jesus to the test. This is why they have said to Jesus "we are legion", and it is common for them to speak in that way, knowing that they have no strength on their own (consider Luke 11:23). It is also common for them to give honour to God The Father, although being clearly of a fallen nature in the eyes of the sanctified.
Adonai works everything out for his own purpose—even the wicked for a day of disaster.
Proverbs 16:4
This "day of disaster" is an enduring truth of the Jewish faith, seen through the stories of Noah, Lot, Job and of course Jesus Christ (1 Thessalonians 2:16, Matthew 7:24-27), whereby Romans 2:9 contains the same warning along the lines of Matthew 3:2, Acts 24:25, Ezekiel 18:26-32 etc.
How horrible for you who look forward to the day of the Eternal One!
Why do you want it to come?
For you, its arrival will mean darkness, not light.
It will be as if you were to escape from a lion
only to run headlong into a bear,
As if you ran into a house to hide, leaned against the wall to rest,
and a poisonous snake latched onto your hand.
Will not the day of the Eternal One be darkness instead of light,
pitch black, without even a hint of brightness?
Amos 15:18-20
Now, this is the mystery of the Christian faith, that we do naturally yearn for the wicked to be blown away (Psalms 139:19-24), yet we are taught to love our enemies, but why? .. and how?
“You have heard that it was said, ‘An eye for an eye, and a tooth for a tooth.’ But I tell you, do not resist an evildoer. But whoever slaps you on your right cheek, turn to him also the other.
Never take your own revenge, loved ones, but give room for God’s wrath—for it is written, “Vengeance is Mine; I will repay,” says Adonai.
Then Yeshua said to him, “Put your sword back in its place! For all who take up the sword shall perish by the sword.
.. and humans are not the only ones who have this sense of justice:
And Adonai said: ‘Who will entice Ahab king of Israel to go up and fall at Ramoth-gilead?’ Then one said this and another said that, until a spirit came forward and stood before Adonai and said, ‘I will entice him.’ So Adonai said to him, ‘How?’ He answered, ‘I will go and be a deceiving spirit in the mouth of all his prophets.’ Then He said, ‘You will entice him and you will also succeed. Go and do so.’
.. and so far as the fallen, who do not receive their instructions from Adonai but are of their father the devil:
You believe that God is one. You do well. The demons also believe—and shudder!
Adonai works everything out for his own purpose—even the wicked for a day of disaster.
Whoever digs a pit will fall in it, and whoever rolls a stone—it will come back upon him.
There is no sorcery effective against Jacob, nor any divination against Israel! Now it will be said of Jacob and Israel, ‘See what God has done!’
.. so, see that our wrestle is not against flesh and blood, but the spiritual hosts of wickedness in the heavenly places. Woe to the earth, for the devil has great fury, knowing that his time is short. As soon as the humans catch on and break free of the illusion, seeing the truth for what it is (2 Thessalonians 2:11-12), then he has no place to go and no-one to represent him.
