International Children’s Bible
8 But the dragon was not strong enough. He and his angels lost their place in heaven. 9 He was thrown down out of heaven. (The giant dragon is that old snake called the devil or Satan. He leads the whole world the wrong way.) The dragon with his angels was thrown down to the earth.
10 Then I heard a loud voice in heaven say:
“The salvation and the power and the kingdom of our God
and the authority of his Christ have now come.
They have come because the accuser of our brothers has been thrown out.
He accused our brothers day and night before our God.
