All this happened to Nebuchadnezzar the king.
Twelve months later (after Daniel's interpretation of the vision) he was walking on the roof of the royal palace of Babylon. The king reflected and said, "Is this not Babylon the great, which I myself have built as a royal residence by the might of my power and for the glory of my majesty?"
While the word was in the king's mouth, a voice came from heaven, saying,
"King Nebuchadnezzar, to you it is declared: sovereighty has been removed from you, and you will be driven away from mankind, and your dwelling place will be with the beast of the field. You will be given grass to eat like cattle, and seven periods of time will pass over you, until you recognize that the Most High is ruler over the realm of mankind, and bestows it on whomever He wishes." Immediately the word concerning Nebuchadnezzar was fulfilled; and he was driven away from mankind and began eating grass like cattle, and his body was drenched with the dew of heaven, until his hair had grown like eagles' feathers and his nails like birds' claws.
