The letter to the church at Pergamos.--2:12-17. 1. “ He which hath the sharp sword with two edges"-- 2:12. The sword is an instrument of war, hence Christ threatened to wage war against the church in Pergamos, because of the evils within it, with the weapon designated “ the sword of my mouth.” A sword of the mouth would necessarily be the spoken word, and it meant the employment of the two-edged sword of his word (Hebrews 4:12), as a dual condemnation of the outside espionage of Satan’ s seat in Pergamos, and the inside sabotage of Balaam’ s doctrine within the church itself--the combined infiltration of pagan secular practices on one hand, and the Nicolaitane spiritual contaminations of erroneous doctrines on the other hand.
