Daniel 5:20-21

20But when his heart was lifted up and his spirit became so proud that he behaved arrogantly, he was deposed from his royal throne and his glory was taken away from him.

21He was also driven from mankind, and his mind was made like that of an animal, and his dwelling place was with the wild donkeys. He was given grass to eat like cattle, and his body was wet with the dew of heaven until he came to know [without any doubt] that the Most High God rules over the kingdom of mankind and He appoints it to whomever He wills.
