Revelation 11:3-4 KJB
"And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. These are the two olive trees, and the two candlesticks standing before the God of the earth."
So who or what are these two witnesses?
The book of Revelation is full of symbolic language. From my understanding these two witnesses are not two literal people.
These two candlesticks and olive trees have multiple interpretations as to what they could represent.
Some of the great theologians have a few theories as to what they symbolize.
"THE TWO Testaments ministering their testimony to the Church of the old dispensation, as well as to that of the new, which explains the two witnesses being called also the two candlesticks (the Old and New Testament churches; the candlestick in Zec 4:2 is but one as there was then but one Testament, and one Church, the Jewish)." -Jamieson-Fausset-Brown commentary on Revelation 11:4
"...the two witnesses as representatives of the Church against the world, but as servants of God, who is here called, accordingly, the Lord of the world, because he shall establish the fact that he is the Almighty, who sends his servants into their office, and protects them against all enemies,..." -Meyer's commentary on Revelation 11:4
