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
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.
