REV 12:10

10 Then I heard [someone] in heaven shout loudly, saying, Now our God has saved his people by his power, and he rules everyone! Now the Messiah, the one who is the supreme ruler whom God appointed, has authority to rule all people, because our God has thrown out of heaven the one who accuses our fellow believers! The dragon is the one who accuses them day and night before our God, saying that they have sinned and that God ought to punish them.
