He suffers from illusions of grandeur....
Typical narcissistic behavior...it’s all about him
Daniel 4:28-33 New International Version (NIV)
The Dream Is Fulfilled
28 All this happened to King Nebuchadnezzar. 29 Twelve months later, as the king was walking on the roof of the royal palace of Babylon, 30 he said, “Is not this the great Babylon I have built as the royal residence, by my mighty power and for the glory of my majesty?”
31 Even as the words were on his lips, a voice came from heaven, “This is what is decreed for you, King Nebuchadnezzar: Your royal authority has been taken from you. 32 You will be driven away from people and will live with the wild animals; you will eat grass like the ox. Seven times will pass by for you until you acknowledge that the Most High is sovereign over all kingdoms on earth and gives them to anyone he wishes.”
33 Immediately what had been said about Nebuchadnezzar was fulfilled. He was driven away from people and ate grass like the ox. His body was drenched with the dew of heaven until his hair grew like the feathers of an eagle and his nails like the claws of a bird.
