Look how the book of Revelation speaks of these 2 men as Witnesses too.
In Revelation 11:3–12 is a description of two individuals who will help accomplish God’s work during the tribulation: “I will appoint my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth” (verse 3). Nowhere does the Bible identify these two witnesses by name, although people through the years have speculated.
