This scripture---absolutely essential in the JW theology about the tree representing God's Kingdom and that that 2,520 years would pass until Jesus started ruling "invisibly" in 1914 is plain horseshit. There is absolutely NOTHING in the book of Daniel to indicate it's referring to anyone else besides Nebuchadnezzar......there's nothing to insinuate that the 7 times means anything other than the 7 literal years that Nebuchadnezzar was bonkers eating or smoking grass and living like an animal.
even if a case could be made, Neb had a fully restored kingdom after his 7 times.... what happened to JC? Got mugged by Satan?
