There are only two of the seven churches commended only for their faithfulness and endurance without receiving a rebuke for anything,
The way it's written in Revelation 11:4 is the same way that Matthew 26:26 & 28 are written:
What represents whom?
Matthew 26
26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body.
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
The bread represents His body, and the wine represents His blood, not the other way around.
Revelation 11:4
These (two witnesses) are the two olive trees, and (they are) the two candlesticks standing before the God of the earth.
Are the two witnesses representing the olive trees and the candlesticks? If so, then you are correct. But if it's the other way around - the two olive trees and the two candlesticks representing the two witnesses, then you are incorrect.
So maybe we should ascertain what is representing whom, or who is representing what in Revelation 11:4, because if they are two individual witnesses then they cannot be represented by only one candlestick or only one olive tree, and they aren't only represented as two candlesticks, as the seven churches in Revelation 1:12-13 & 20 are.
And because no olive trees are mentioned in Revelation 1:12-13 & 20, we cannot use the argument of Gentiles being grafted into the olive tree as in Romans 11, because in Zechariah 4 olive trees (which provide the olives which provide the oil for the candles to burn) are seen beside the candlesticks
- and they "stand before the God of the earth" - just like Zechariah 4's two "sons of the anointing".
But Zechariah 4 is all about the building of God's Temple, and Zerubbabel is a type of Christ who builds His churches "Not by might, nor by power, but by My Spirit". (which I assume means not by human might or power):
And out of the throne proceeded lightnings and thunderings and voices: and there were seven lamps of fire burning before the throne, which are the seven Spirits of God. Rev 4:5
And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. Rev 5:6
For who hath despised the day of small things? for they shall rejoice, and shall see the plummet in the hand of Zerubbabel with those seven; they are the eyes of the Lord, which run to and fro through the whole earth. Zech 4:10.
All of the above points to the two witnesses representing churches, but there is also the following:
A BIBLICAL TYPE
In the days leading up to the deliverance of God's people through the sea, Moses and Aaron were God's two witnesses in Egypt, who had power over waters to turn them to blood, and to smite the earth with all (sorts of) plagues, and though it be only a type, they were only two individuals, not many individuals.
So we need to ascertain what is representing whom, or who is representing what in Revelation 11:4.
