Jamieson, Fausset and Brown on Revelation 12:17

17. wroth with--Greek, "at."

went--Greek, "went away."

the remnant of her seed--distinct in some sense from the woman herself. Satan's first effort was to root out the Christian Church, so that there should be no visible profession of Christianity. Foiled in this, he wars (Re 11:7; 13:7) against the invisible Church, namely, "those who keep the commandments of God, and have the testimony of Jesus" (A, B, and C omit "Christ"). These are "the remnant," or rest of her seed, as distinguished from her seed, "the man-child" (Re 12:5), on one hand, and from mere professors on the other. The Church, in her beauty and unity (Israel at the head of Christendom, the whole forming one perfect Church), is now not manifested, but awaiting the manifestations of the sons of God at Christ's coming. Unable to destroy Christianity and the Church as a whole, Satan directs his enmity against true Christians, the elect remnant: the others he leaves unmolested.
