Revelation 12:7-9
The Angel, Michael
7 And war broke out in heaven, Michael [the archangel] and his angels waging war with the dragon. The dragon and his angels fought,
8 but they were not strong enough and did not prevail, and there was no longer a place found for them in heaven.(A)
9 And the great dragon was thrown down, the age-old serpent who is called the (a)devil and Satan, he who continually deceives and seduces the entire inhabited world; he was thrown down to the earth, and his angels were thrown down with him.(B)

Revelation 12:9: The Greek for devil is diabolos, which is actually a translation of Satan, a Hebrew word meaning “adversary” or “accuser.” The Greek word additionally carries with it the concept of “slanderer.” See note v 10.
