There are several good reasons to believe that the Tree Dream described in Daniel 4 has both a typical and anti-typical fulfillment and I list these some of these reasons as follows:
Another good scripture is Ezekiel 21:10 where the sword of Nebuchadnezzar is said to ignore the scepter of God's own son as it ignores a tree.
“Say, ‘A sword, a sword! It has been sharpened, and it is also polished. 10 For the purpose of organizing a slaughter it has been sharpened; for the purpose of its getting a glitter it has been polished.’”’”
“Or shall we exult?”
“‘Is it rejecting the scepter of my own son, as [it does] every tree?
19 “And as for you, O son of man, set for yourself two ways for the sword of the king of Babylon to enter.
So the sword of Babylon cuts down the scepter of God's representative kingdom on the earth, which is likened to cutting down a tree; thus the kingship of Judah is likened to a tree that is cut down by Babylon.
In addition, Nebuchadnezzar is called God's "servant" and thus he himself in a sense represents the messiah. So his seven years of being off the throne could also refer to a kingly representative sitting on God's throne for "7 times."
So in this case, there is a considerable comfort zone is expanding this prophecy as a reference to someone sitting on the earthly throne of king David or at least a king to be present in the earth who will first rule in the midst of his enemies.
But that brings up another aspect of this prophecy. That is, it makes sense if Christ returns in the flesh, becoming a human representative on the earth of God's kingdom represented by the Judean kings. It gets a little confusing when Christ never returns in the flesh and he rules from heaven as the WTS now teaches and thus there is never an earthly representative of the kingdom again.
It also is more consistent with the representation if when Jesus returns he returns in the flesh so he can be said to be "ruling in the midst of his enemies", meaning upon his return he does not immediately sit on the throne of king David when he arrives. Christ returning in 1914 invisibly and still in spirit form does not parallel well with the physical interruption of an earthly representative. Whereas, when Jesus actually returns in the flesh and is back on the earth again, there is a more symmetrical parallel in terms of a JW-concept, that of a recognize king in the earthy sitting on Jehovah's representative throne.
Also, there are two bands used to stop the tree's growth. One of iron and one of copper. These represent the two messiahs. The messiah of the first coming, coming through the line of Judah and being typically Jewish, meaning fair and white. But the second coming of copper is through the line of Joseph whose children were half Egyptian. Thus the copper banding represents the darker complexion of the messiah at the second coming.
So it is interesting the WTS clearly understands how to apply the double fulfillment here and how to calculate 2520 years from the fall of Jerusalem and removal of the king, and understands that the throne will be left desolate until he who has the legal right appears, who is the messiah, but does not understand that that messiah fulfills the return by actually showing up in the flesh to rule on the earth for 1000 years. Instead, because he didn't show up in 1914, they claim he is invisibly ruling from the heavens in the midst of his enemies. How can Jesus be in the "midst of his enemies" if he is safe and far away safe in heaven? That is, compared to his having returned a second coming in the flesh where the messiah-king is actually on the earth where his enemies are and thus could be literally said to be ruling in their midst.
In other words, the 2520 years represents a period when there would be no representative human king on the earth sitting on God's representative throne. No man was to be recognized as sitting on God's throne until the messiah arrives. If Jesus comes back in the flesh, then that 2520-year interruption makes sense. It actually separates two fleshly kings. When Jesus simply rules from heaven then there still remains no earthly representative of the kingdom. The 2520 years was meant to separate the rule of two earthly kings.
