In reply to your 3/28 post at http://www.fivedoves.com/letters/mar2021/gino328-2.htm the fallen angels who had sex with the daughters of men are already in hell awaiting the day of judgment which I am assuming is the great white throne judgment at which time they would be tossed into the lake of fire.  Please see the Bible verses below in regards to these fallen angels:

2 Peter 2:4, "For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;"

2 Peter 2:9, "The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:"

Jude 1:6, "And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day."

As for the other fallen angels who are cast out of heaven with Satan onto the Earth in Rev. 12:7-9, the Bible does not say when these other fallen angels are cast into the lake of fire and brimstone although we know that Satan is bound for a 1,000 years in the bottomless pit so that he can't deceive the nations, and then he is loosed for a little season after the 1,000 years to deceive the nations after which time he is cast into the lake of fire and brimstone according to Rev. 20:1-10.
