Revelation, as we all should know, speaks in apocalyptic language, so a literal interpretation for many of the things we find in this book is by far out of the question. For example, who ever saw a wild beast with more than one head? Who ever saw an animal with 10 horns? These among other things in Revelation show one must not take the things we find here in a literal manner. But, if this is so, how should we understand these things without permitting our imaginations to run wild? In order to keep its readers from placing our own individual interpretation upon the meaning of Scripture, Scripture, itself, often defines its own terms. For example, Daniel 7:24 defines a horn as a king or ruler, as does Revelation 17:12. So, how should we understand the ‘mouth’ of Revelation 13:5? Quoting the Scripture in its context:
And there was given unto him [the Beast – v.4] a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months. And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven. And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations. And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. If any man have an ear, let him hear. He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints. (Revelation 13:5-10 KJV) — brackets mine
The Beast as I claimed in The Seven Headed Beast of Revelation 13 is apostate Jerusalem. The Beast can exist only when the Jews have a nation. The deadly wound represents the time the Jews were in exile in Babylon. Up to the time of Cyrus, this was how all warfare was conducted against rebellious and conquered nations. If the nation didn’t submit, they were removed from their lands and others were eventually placed there. Cyrus was the first ruler to grant a release and permit his captive subjects such as the Jews to return to their homelands. Thus their return under Zerubbabel and almost immediate apostasy represented the healing of the Beast’s deadly wound. The ‘mouth’ of Revelation is the one giving expression to apostate Judaism. How was this done?
The ‘mouth’ spoke great blasphemies and authority was given him to ‘continue’ for 42 months (v.5). The word translated continue is so translated only here. It is poiesai (G4160), and means “to act, work, make.” The question is to act, work or make what? The context of Revelation 13:4, 7 would seem to indicate making (war), specifically with the “saints” or Messianic Jews (Revelation 13:7). That is, the ‘mouth’ or spokesman of the Beast (apostate Judaism) was given authority over all Messianic Jews no matter which “kindred” (tribe), language spoken and no matter where in the Empire they had settled. Moreover, all the Jews of the land (Palestine) will worship him. That is, they will worship the Beast (apostate Judaism) by obeying the authority of the spokesman—i.e. apostate Judaism’s mouth. Only those Jews who are Messianic—i.e. who have believed in Jesus as their Savior and Messiah—will not worship the Beast or apostate Judaism. It is these Jews with whom the Beast (apostate Judaism) will make war at the command of their spokesman.
So, who is this mouth? It is Annas the high priest who had Jesus crucified. He is the False Prophet (Revelation 13:11-18; 16:13; 19:20; 20:10) and the Man of Sin (2Thessalonians 2:3) to whom the New Testament refers. I understand this is not a view held my most Christians today, but it fits, nevertheless. Annas made it his personal vendetta not only to crucify Jesus, but to hunt down and persecute Jewish believers in Jesus all over the Promised Land and, eventually, into all the Roman Empire. His final surge of persecution involved starving the Messianic priests who served in the Temple, killing James (the brother of the Lord) and undertaking an empire-wide effort to destroy the Church of God. This final effort incorporated a 3 ½ year period that culminated in his own death and the beginning of the Jewish war with Rome. In future blogs I plan to show how all this is true. May God help me to seek only that which is true and enable me to write with clarity.
 B (Vaticanus) reads, “to make war” (compare Revelation 13:4, 7). But A (Alexandrinus), C (Codex Bezae), Vulgate, Syriac, and ANDREAS omit “war.”
 See Josephus: Wars 2.17.1 through 10. The entire 17th chapter tells of the beginning of the Jew’s war with Rome. The High Priest, Ananias, spoken of there and killed in the fight is the same Annas who had Jesus crucified. Ananias is another way of spelling or pronouncing his name see Josephus: Antiquities; 20.9.1 where it tells of Ananus, the son of Ananus, killing James (the brother of Jesus). Here is another spelling of the same name, which is made even clearer in Antiquities 20.9.3.
