What is the source for quantifying that a third of angels fell with Satan?

I think that might be associated with the book of revelations which says that a third of the stars fell from the sky.

to me it is means that the angels that chose to delight themselves in the physical world (which is one third) became evil

while the angels that govern the seas (the worlds)

and the skys (the heavens)

remained good.

1. Jude 1:6 2Peter 2:4

2. The Apocrypha

3. Non-standard biblical texts around the world

4. The Urantia Book

Supporting this are the apostle Peter’s references to “the spirits in prison, who had once been disobedient when the patience of God was waiting in Noah’s days” (1Pe 3:19, 20), and to “the angels that sinned,” mentioned in connection with the “ancient world” of Noah’s time (2Pe 2:4, 5), as well as Jude’s statement concerning “the angels that did not keep their original position but forsook their own proper dwelling place.” (Jude 6) If it is denied that “the sons of the true God” of Genesis 6:2-4 were spirit creatures, then these statements by the Christian writers become enigmatic, with nothing to explain the manner in which this angelic disobedience took place, or its actual relation to Noah’s time.

Scripture is the source. When Satan fell from heaven, he took one third rebellious angels with him, sweeping them down with his tail apparently, according to scripture. (Revelation 12:4)

(Revelation 12:3, 4) And another sign was seen in heaven, and, look! a great fiery-colored dragon, with seven heads and ten horns and upon its heads seven diadems; 4 and its tail drags a third of the stars of heaven, and it hurled them down to the earth. And the dragon kept standing before the woman who was about to give birth, that, when she did give birth, it might devour her child.

(Jude 6) And the angels that did not keep their original position but forsook their own proper dwelling place he has reserved with eternal bonds under dense darkness for the judgment of the great day.

Revelation 12 : 3-9

The Book of Revelation deals primarily with Biblical symbolism. In order to understand this book it is vital to have a solid understanding of symbolism in scripture from Genesis on ward.

Lots on information on Christian Eschatology available online.

Simply because the offering is a limited Ploy to hinder Thought, as the Numbers in fact are still in Growth, based upon the percentage of any Earthly Culture being infested by the Beastly Nature of ( Mental illness ) of SATANISM; and as the Number of ANGELS increase right here upon the Earth, and right in front of your closed Eyes. 0107.2016

It is in the Book of Revelation.

Rev 12:4

His tail drew a third of the stars of heaven and threw them to the earth.

never true satan is from Jenns / spirits

Muslim

And [mention] when We said to the angels, "Prostrate to Adam," and they prostrated, except for Iblees. He was of the jinn and departed from the command of his Lord. Then will you take him and his descendants as allies other than Me while they are enemies to you? Wretched it is for the wrongdoers as an exchange.

Bascially it's John cross-reference Dan 8:10 and jazzing it up a bit whilst getting it wrong.
