Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
Repent,.... This is said to those who were truly godly in those times, but still retained their communion with these corrupt men, and had not, as yet, separated from then; nor had they protested against these evil doctrines and practices, at least but very coldly, and had too much connived at them; and therefore are called upon to repent of their lukewarmness, negligence, and sinful compliances:
or else I will come unto thee quickly: in a providential way, to rebuke and chastise for such remissness, indifference, and evil communication:
and will fight against them with the sword of my mouth; of this sword, See Gill on "Revelation 1:16". And it is observable, that Christ does not say, "I will fight against thee"; the true members of his mystical body, though lax and supine, for Christ does not fight against his people, but for them; but he says, "and will fight against them"; the Balaamites and Nicolaitans, for their idolatry and uncleanness.
