Revelation 12:8 In-Context

6 The woman fled into the wilderness to a place prepared for her by God, where she might be taken care of for 1,260 days.
7 Then war broke out in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back.
8 But he was not strong enough, and they lost their place in heaven.
9 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.
10 Then I heard a loud voice in heaven say: “Now have come the salvation and the power and the kingdom of our God, and the authority of his Messiah. For the accuser of our brothers and sisters, who accuses them before our God day and night, has been hurled down.
