They are described as individuals in revelation. And Zechariah says "two anointed ones", and Haggai is also about two specific individuals who lead the Remnant in building the House of God. And Zechariah says prophetically that zerubbabel's hands laid the foundation and his hands will finish it.
The Two are also shadow pictured in several other places. Moses and Aaron, Zerubbabel and Jeshua, etc. These Two are also "clothed is sackcloth".
So with the Word repeatedly referencing two individuals, why do some people insist they are not?
Is there a truly scriptural reason for this?
Churches do refer to bodies of people, but the two bodies of people "House of Judah and House of Israel" are not churches. They are families who are brought together under one head (Hosea 1).
And BTW, Judah is saved at that time and Israel is all who are called sons of the living God. That's a reference to the adoption thorough Christ Jesus (Lion of Judah). So when these two anointed ones are giving their Testimony, they are united under one Head. That means we are finally one body. Not two.
It is good for us to be seeking truth about this because they do play a very important role in this time very near. They lead every tribe, tongue and nation (who reject the beast, whose names are written in the book of life) to take great action and exploits against the antichrist system. To the point that their slaying is celebrated by the wicked.
And the while world sees their bodies last dead for 3.5 days.
