Revelation 12:11

And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.

They - in particular; emphatic, 'they alone.'

Overcame - (Romans 8:33; Romans 8:37; Romans 16:20.)

Him - (1 John 2:14.) It is the same victory over Satan and the world which John's gospel describes in the life of Jesus, his letter in each believer's life, and his apocalypse in the life of the Church.

By, [ dia (G1223) to (G3588) haima (G129): accusative, not genitive, as "by" would require: cf. Hebrews 9:12 ] - 'on account of (on the ground of) the blood of the Lamb:' by virtue of its having been shed. Had it not been shed, Satan's accusations would have been unanswerable: that blood meets every charge. Schottgen mentions the Rabbinical tradition that Satan accuses men all days of the year, except the day of atonement. Tittmann less probably takes [ dia (G1223)] out of regard to: the blood of the Lamb induced them to undertake the contest for the sake of it.

By (on account of) the word of their testimony. On the ground of their faithful testimony they are constituted victors. It evinced their victory. Hereby they confess themselves worshippers of the slain Lamb, and overcome the beast, Satan's representative: an anticipation of Revelation 15:2 (cf. Revelation 13:15).

Unto, [ achri (G891)] - 'even as far as.' They carried their not-love of life as far as even unto death.
