"is the earthly mount Zion after the pattern of the heavenly mount Zion?"

As the tabernacle was to be made after the pattern of that which is heaven,
is the earthly mount Zion after the pattern of the heavenly mount Zion?

Hebrews 12:22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,

Revelation 14:1 And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Fatherís name written in their foreheads.

Jesus isn't coming back to stand on mount Zion on earth, in the middle of the tribulation, before his second advent?
Isn't Revelation 14:1 referring to the mount Zion in heaven?
On earth there is a Salem and a Zion, is it not also true in heaven?

Revelation 3:12c  and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God:

Psalms 76:2 In Salem also is his tabernacle, and his dwelling place in Zion.

If so, then Melchizedek wouldn't have been an heathen Jebusite king, but rather a priest of God from the heavenly Salem?

Genesis 14:18 And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.

Hebrews 7:1 For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;
  2 To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;

If so, then it would make more sense about what he did and what Abraham did.
It would also make the following easier to understand:

Hebrews 7:3 Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
  4 Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.
  15 And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest,
  16 Who is made, not after the law of a carnal commandment, but after the power of an endless life.
  17 For he testifieth, Thou art a priest for ever after the order of Melchisedec.

If Melchisedec was without father or mother, then he wasn't Canaanite, or Jebusite, was he?
If he had no end of life, but if he was from the earthly Jebusite city,
wouldn't he still have been alive and been king when the Jebusites attacked Gibeon?

Joshua 10:5 Therefore the five kings of the Amorites, the king of Jerusalem, the king of Hebron, the king of Jarmuth, the king of Lachish, the king of Eglon, gathered themselves together, and went up, they and all their hosts, and encamped before Gibeon, and made war against it.

Or after the battle with Joshua, hiding in the cave?

Joshua 10:17 And it was told Joshua, saying, The five kings are found hid in a cave at Makkedah.

Or when the Jebusites mocked David to come and take the city?

II Samuel 5:6 And the king and his men went to Jerusalem unto the Jebusites, the inhabitants of the land: which spake unto David, saying, Except thou take away the blind and the lame, thou shalt not come in hither: thinking, David cannot come in hither.
  7 Nevertheless David took the strong hold of Zion: the same is the city of David.
