And the dragon was wroth with the woman
The devil was very angry with the church, because he could not destroy her by the Arian persecution he had raised; and because he could not carry her away with the flood, either of errors and heresies, or of the barbarous nations; and because he could not, by any means, come at her, and indeed did not well know where she was, a place being prepared for her of God in the wilderness, where she was taken care of: wherefore he took another method as follows,
and went to make war with the remnant of her seed;
which refers to the war the beast, to whom he gave his power, seat, and authority, is said to make with the saints; and which was entered into and carried on by his instigation, of which there is an account in the following chapter: the persons with whom he went to make war are described as "her seed"; the seed of the church, her spiritual offspring, the sons and daughters she brought forth to Christ; between which seed, and Satan and his seed, there always was an enmity: and these are "the remnant" of her seed, a few persons scattered up and down, a remnant according to the election of grace; who were not in bodies, or in church states, regularly formed, as heretofore, but in private families, and some here, and some there; and who were called out to bear a testimony for Christ in corrupt times: and these are further described as such
who keep the commandments of God:
and not the traditions of men: nor are the commands of the moral law of God so much designed, though it is true that these were kept by the seed of the church; but rather the ordinances of the Gospel, the commands of God our Saviour, such as baptism and the Lord's supper; which were kept by these faithful ones, as they had been delivered, when they began now to be sadly corrupted by the antichristian party:
and have the testimony of Jesus Christ;
the Gospel, which is a testimony concerning him; (See Gill on Revelation 1:2). This they had in their hearts, a spiritual knowledge and saving experience of it; and this they had in their hands, they made a profession of it, they held it forth, and held it fast; all which was the reason of Satan's enmity against them, and war with them.
