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," Numbers 22:23, and afterwards "slain with the sword," Numbers 31:8.
