Revelation 12:10-11Expanded Bible (EXB)
10 Then I heard a loud voice in heaven saying:
“The salvation and the power and the kingdom of our God
and the ·authority [power] of his ·Christ [Messiah; Anointed One] have now come [
Dan. 7:14].
[L For] The accuser [C the name Satan means “Accuser” in Hebrew;
Job 1:6–12;
2:1–6;
Zech. 3:1–2] of our brothers and sisters,
who accused them day and night before our God,
has been ·thrown [cast; hurled] down.
11 And
our brothers and sisters ·defeated [conquered] him
by the blood of the ·Lamb’s death [L Lamb; C by means of Christ’s sacrificial death]
and by the ·message they preached [L word of their witness/testimony].
[L And] They did not love their lives so much
that they ·were afraid of [avoided] death.
