“Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.”
King James Version (KJV)
2:16 If not, I come to thee - who wilt not wholly escape when I punish them. And will fight with them - Not with the Nicolaitans, who are mentioned only by the by, but the followers of Balaam. With the sword of my mouth - With my just and fierce displeasure. Balaam himself was first withstood by the angel of the Lord with his sword drawn, #Num 22:23|, and afterwards slain with the sword, #Num 31:8|.
Re 2:16 Repent. This may save the sinner, whether an alien, or a church member. To repent one must leave off his sins. Will fight against them. Those who teach and practice these pernicious doctrines. With the sword of my mouth. See Re 1:16. With all the power of the word of God.
