Some dispute Moses will be one of them interpreting “it is appointed unto men once to die” ruling that out (Deut. 34:5-7). However, that general statement about life shows this in correspondence with Christ being offered once for sins (Heb. 9:25-26). Its clearly not meant to contradict common knowledge everyone raised from the dead in the Bible (except Christ) died again (1 Ki. 17:22; 2 Ki. 13:21; Mark 5:41; John 12:17; Ac. 9:40) died more than once.
They are modeled after Moses and Elijah in Revelation 11:6. Like Moses they turn water into blood and strike the earth with plagues (Ex. 7:14:25), like Elijah they can cause drought during their prophesying (1 Ki. 17:1-7; 18:1; 41-46). Perhaps the redeemed singing the son of Moses is relevant here (Rev. 15:3). Satan may have wanted to prevent the resurrection of Moses precisely to prevent this appearance in the end time (Jude 1:9). The identity of Elijah is confirmed by direct prophecy (Mal. 4:5-6; Mt. 17:10, 11) and calling down fire from heaven (1 Ki. 18:36). The appearance of Moses and Elijah at Christ’s transfiguration seems pertinent here, these are clearly a “power duo” (Mt. 17:3-4; Mk. 9:4-5; Lk. 9:30-33). Collaborating Moses and Elijah were physically present on the Mount of Transfiguration is Peter’s desire to build tents for them (Mk. 9:4-5).
Moses and Elijah are the perfect fit for calling the Elect of God both Jew and Gentile to repentance. Sackcloth symbolizing a call for all to repent will be a major theme of their prophesy.
It is likely the fallen away church would resent the appearance of the two witnesses and declare them frauds seeking to silence them. But all who receive their testimony and believe on the LORD Jesus Christ will be filled by the Holy Spirit as symbolized by their having an inexhaustible supply of oil as the two olive trees of the LORD (Rev. 11:4; Zech. 4:1-14)
At the end of their witnessing they are slain by Emperor Adonikam whose ascension out of the Abyss symbolizes his claim to be an Extraterrestrial hybrid of the “creators” (Rev. 11: 7; 9:1-3) superior to them all, especially “YHWH one of the creators”, that strong delusion buttressed by lying signs and wonders (2 Thess. 2:9-12; Rev. 16:13).
The command to kill Christ originated in Jerusalem (Mt. 23:34-39; 27:24-25; Ac. 2:23) so it could be said Jesus was crucified in the city of Jerusalem. John says the city “spiritually is called Sodom and Egypt” which fits perfectly what Jerusalem had become, a city in league with the Beast. No longer a “holy city”, it now fit the description of that “great city Babylon” filled will all sorts of idolatry and perversion.
