Revelation 2:16 Meaning and Commentary

Revelation 2:16

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:

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;

15 so hast thou, even thou, those holding the teaching of the Nicolaitans -- which thing I hate.
16 `Reform! and if not, I come to thee quickly, and will fight against them with the sword of my mouth.
17 He who is having an ear -- let him hear what the Spirit saith to the assemblies: To him who is overcoming, I will give to him to eat from the hidden manna, and will give to him a white stone, and upon the stone a new name written, that no one knew except him who is receiving [it].
18 `And to the messenger of the assembly of Thyatira write: These things saith the Son of God, who is having his eyes as a flame of fire, and his feet like to fine brass;
