What the Bible says about Stars as Symbols of Angels

Revelation 12:4

Revelation 12:4 suggests an aspect of an angel's capacity. In biblical imagery, "stars" are symbols of angels. The verse implies that Satan coerced a third of these great beings to choose to submit to him and follow him in resisting God Himself as well as the outworking of His purpose in us. The Devil's persuasion and the angels' subsequent choices occurred in the distant past, and those who submitted to him are now demons against whom we wrestle (Ephesians 6:12).

Revelation 12:4

Stars, a symbol of angels, is used, meaning his angels—demons—were cast out with him. The Devil and his angels were cast to the earth. We have insight here into a major battle that took place in heaven, one that Satan and his angels lost, and they were cast to the earth. Unfortunately, that is where we live.
