It says that he took a 3rd of the stars, stars could mean anything. Is there any other verses in the bible that talk about the fall of Satan's angels as well.
Hello finaldesire,
Here in Revelation 12, the context itself reveals the symbolism of the stars. See the following:
"Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on its heads. Its tail swept a third of the stars out of the sky and flung them to the earth."
"Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But he was not strong enough, and they lost their place in heaven. The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him.
Revelation 12 verses 1 thru 6 is a summary, where verse 7 thru 17 is a detailed account.
A third of the stars being flung to the earth, is synonymous with Satan and his angels being flung to the earth.
If you'll notice in verse 4, the dragon's tail flings a third of the stars to the earth, then in verse 9 the dragon is identified as Satan, with the symbolism of the stars being revealed as "his angels" who are hurled to the earth with him.
Therefore, the context identifies the dragon as representing Satan and the stars are symbolic representing his angels.
