The following is stated about Jesus in the first chapter of Revelation which becomes relevant to His message to Pergamum.

Revelation 1:16 And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength. (KJV)

Jesus tells us the meaning of the seven stars in this verse, but He says nothing concerning the sharp two edged sword, why might that be? Perhaps it is because we should actually know from scripture what the sword is. In Eph. 6:17 we are told to take the sword of the spirit which is the word of God. We also know that He is the word made flesh, and by His word He created and with His word He will destroy. So when He says:

Revelation 2:12 And to the angel of the church in Pergamos write; These things saith he which hath the sharp sword with two edges; (KJV)

Revelation 2:16 Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth. (KJV)

Jesus calls Pergamum to repentance, and short of repentance in their lives His promise is to come to them fighting with the sword of His mouth. There are other clues in the Revelation that would be an indication of when that might be:

Revelation 19:15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. (KJV)

Revelation 19:21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh. (KJV)

Jesus will come as seen in Revelation 19 with the wrath of God in judgment.

Hebrews 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. (KJV)

When the apostle Paul tells us not to dispute over words, is it not because God’s word is clear and it being “the truth” needs no one to debate it, as it needs no addition to nor subtraction from in order to be understood.

Take heed to Jesus words in Revelation 22:18-19.

Is there a message in this concerning the timing of judgment and rewards for the church at Pergamum?

He who has ears let him hear what the Spirit saith unto the churches.
