In the Chronological Bible commentary for today are these words.  "After Ezekiel's great temple vision, it is another two years before the word of the Lord comes to him again".   Just because it isn't recorded doesn't mean God didn't speak to him.

Nebuchadnezzar has a dream that Daniel interprets for him. The king is given another chance to repent which he doesn’t do. The dream becomes reality as the king is reduced to living with wild animals. Some think this was a form of mental illness called lycanthropy, which is "a form of madness involving the delusion of being an animal, usually a wolf, with correspondingly altered behavior." This illness lasted “seven times” which means seven years.

"the Most High is sovereign over the kingdoms of men and gives them to anyone he wishes and sets over them the lowliest of men." 

You can make your own connections to some of the leaders of the U.S, today in reference to "the lowliest of men". Companion verse is found in Romans 13:1.

Nebuchadnezzar was king of Babylon which was founded by Nimrod, the great-grandson of Noah. The city was surrounded by a wall 350 feet high and 87 feet thick and wide enough for six chariots to drive abreast. There were 250 watchtowers on top of the wall and it was surrounded by a moat.

Nebuchadnezzar, who has spent most of his life oppressing God’s people, ends his life well. Compare him to the apostle Paul.

When the king raised his eyes toward heaven, his sanity was restored and he praised God. Doesn’t that sound as if it is something we should all do…raise our eyes toward heaven and give praise to Him? When our eyes are on the world around us, we can easily become insane. It’s only when we look toward God and our eternal future with Him, that we are truly sane! Amen???
