How do you know that? Hebrews was written after Zechariah, after all the facts were known about God's entire salvation program. In fact the entire book of Hebrews is devoted to teaching that all the types here on earth were mere pictures of the reality in heaven. E.g.,
1 Now this is the main point of the things we are saying: We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, 2 a Minister of the sanctuary and of the true tabernacle which the Lord erected, and not man. 3 For every high priest is appointed to offer both gifts and sacrifices. Therefore it is necessary that this One also have something to offer. 4 For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; 5 who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, "See that you make all things according to the pattern shown you on the mountain." (Heb. 8)By empathizing the earthly Jerusalem you are only concerned about the copy, which was temporary and carnal (Gal. 4). The proof is obvious, just look to the NT to find any suggestion that earthly Jerusalem has an eschatological future.
All you have succeeded in doing is demonstrating the failure of the dispensational system to take all of the Bible into account when interpreting passages.
Well once again all that you have succeeded in doing is demonstrating your inability to read and understand words properly, especially those in Hebrews. The author of Hebrews is talking about "the priests and things in the tabernacle that are a copy and shadow". He is not talking about Jerusalem which was not built after the heavenly Jerusalem. The City of David was not built as a copy or shadow of the heavenly Jerusalem above.
You really need to quit stretching things --
