“And I will give unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. 4. These are the two olive trees and the two candlesticks, standing before the Lord of the earth. 5. And if any man desireth to hurt them, fire proceedeth out of their mouth and devoureth their enemies; and if any man shall desire to hurt them, in this manner must he be killed. 6. These have the power to shut the heaven that it rain not during the days of their prophecy: and they have power over the waters to turn them into blood, and to smite the earth with every plague, as often as they shall desire. 7. And when they shall have finished their testimony, the beast that cometh up out of the abyss shall make war with them, and overcome them, and kill them. 8. And their dead bodies [lie] in the street of the great city, which spiritually is called Sodom and Egypt, where also their Lord was crucified. 9. And from among the peoples and tribes and tongues and nations do [men] look upon their dead bodies three days and a half, and suffer not their dead bodies to be laid in a tomb. 10. And they that dwell on the earth rejoice over them, and make merry; and they shall send gifts one to another; because these two prophets tormented them that dwell on the earth. 11. And after the three days and a half the breath of life from God entered into them, and they stood upon their feet; and great fear fell upon them that beheld them. 12. And they heard a great voice from heaven saying unto them, Come up hither. And they went up into heaven in the cloud; and their enemies beheld them.”
Revelation 11: 3.
While it is impossible to be dogmatic about the specific identity of these two preachers, there are a number of reasons that suggest that they may be Moses and Elijah.
Moses and Elijah are seen as possibilities for the two witnesses due to the specific miracles that John says the witnesses will perform. The witnesses will have the power to turn water into blood (Revelation 11:6), which duplicates a famous miracle of Moses, who turned the waters of the Nile into blood (Ex. 7:17–21). Moses also announced the other plagues on Egypt recorded in Exodus chapters 7–12.
The witnesses will have the power to destroy their enemies with fire (Revelation 11:5), which corresponds to an event in Elijah’s life as recorded in 2 Kings 1: 10-14; and Elijah pronounced a three-and-one-half-year drought on the land (1 Kings 17:1; James 5:17) which is the same length as the drought brought by the two witnesses (Rev. 11:6).
Also giving strength to this view is the fact that Moses and Elijah both appeared with Jesus at the transfiguration (Matthew 17:3–4). Based on the prophecy of Elijah’s coming in Malachi 4:5 and God’s promise to raise up a prophet like Moses (Deuteronomy 18:15 – 18), some Jews believe that these scriptures necessitates Moses’ return. Again, both the Old Testament and Jewish tradition expects Moses and Elijah to return in the future.
Malachi 4:5 predicted the return of Elijah, and the Jews believed that God’s promise to raise up a prophet like Moses (Deut. 18:15, 18) necessitated his return (cf. John 1:21; 6:14; 7:40).
Third, both Moses and Elijah (perhaps representing the Law and the Prophets) appeared with Christ at the Transfiguration, the preview of the Second Coming (Matt. 17:3?).
We understand that Moses and Elijah left the earth in unusual ways. Elijah never died, but was transported to heaven in a fiery chariot (2 Kings 2:11–12), and God supernaturally buried Moses’ body in a secret location (Deut. 34:5–6; Jude 9). The statement of Hebrews 9:27 that “it is appointed for men to die once and after this comes judgment” does not rule out Moses’ return, since there are other rare exceptions to that general statement (such as Lazarus; John 11:14, 38–44), and of course, the witnesses themselves will die and come back to life after three and a half days (Rev. 11:7-11)
Since the text does not specifically identify these two preachers, the view defended above, like all other views regarding their identity, must remain speculation.
Enoch and Elijah are seen as possibilities for the two witnesses because of the unique circumstances surrounding their exit from the world. Enoch and Elijah, as far as we know, are the only two individuals whom God has taken directly to heaven without experiencing death (Genesis 5:23; 2 Kings 2:11). Proponents of this view point to Hebrews 9:27, which say that all men are appointed to die once. Many believe that this passage of scripture and the fact that neither Enoch nor Elijah has yet experienced death seems to qualify them for the job of the two witnesses, who will be killed when their job is done. In addition, both Enoch and Elijah were prophets who pronounced God’s judgment (1 Kings 17:1; Jude 1:14–15).
So who are the two witnesses of Revelation? The Bible does not say!
