Daniel 4:32-33

32and you will be driven away from mankind, and your dwelling place will be with the animals of the field. You will be given grass to eat like the cattle, and seven periods of time will pass over you until you know [without any doubt] that the Most High God rules over the kingdom of mankind and He bestows it on whomever He desires.” ’

33Immediately the word concerning Nebuchadnezzar was fulfilled. He was driven away from mankind and began eating grass like cattle, and his body was wet with the dew of heaven until his hair had grown like eagles’ feathers and his nails were like birds’ claws.
