13. unclean spirits like frogs--the antitype to the plague of frogs sent on Egypt. The presence of the "unclean spirit" in the land (Palestine) is foretold, Zec 13:2, in connection with idolatrous prophets. Beginning with infidelity as to Jesus Christ's coming in the flesh, men shall end in the grossest idolatry of the beast, the incarnation of all that is self-deifying and God-opposed in the world powers of all ages; having rejected Him that came in the Father's name, they shall worship one that comes in his own, though really the devil's representative; as frogs croak by night in marshes and quagmires, so these unclean spirits in the darkness of error teach lies amidst the mire of filthy lusts. They talk of liberty, but it is not Gospel liberty, but license for lust. There being three, as also seven, in the description of the last and worst state of the Jewish nation, implies a parody of the two divine numbers, three of the Trinity, and seven of the Holy Spirit (Re 1:4). Some observe that three frogs were the original arms of France, a country which has been the center of infidelity, socialism, and false spiritualism. A and B read, "as it were frogs," instead of "like frogs," which is not supported by manuscripts. The unclean spirit out of the mouth of the dragon symbolizes the proud infidelity which opposes God and Christ. That out of the beast's mouth is the spirit of the world, which in the politics of men, whether lawless democracy or despotism, sets man above God. That out of the mouth of the false prophet is lying spiritualism and religious delusion, which shall take the place of the harlot when she shall have been destroyed.
      the dragon--Satan, who gives his power and throne (Re 13:2) to the beast.
      false prophet--distinct from the harlot, the apostate Church (of which Rome is the chief, though not sole, representative), Re 17:1-3, 16; and identical with the second beast, Re 13:11-15, as appears by comparing Re 19:20 with Re 13:13; ultimately consigned to the lake of fire with the first beast; as is also the dragon a little later (Re 20:10). The dragon, the beast, and the false prophet, "the mystery of iniquity," form a blasphemous Antitrinity, the counterfeit of "the mystery of godliness" God manifests in Christ, witnessed to by the Spirit. The dragon acts the part of God the Father, assigning his authority to his representative the beast, as the Father assigns His to the Son. They are accordingly jointly worshipped; compare as to the Father and Son, Joh 5:23; as the ten-horned beast has its ten horns crowned with diadems (Greek, Re 13:1), so Christ has on His head many diadems. While the false prophet, like the Holy Ghost, speaks not of himself, but tells all men to worship the beast, and confirms his testimony to the beast by miracles, as the Holy Ghost attested similarly to Christ's divine mission.
