Daniel 4:33

that you be driven away from mankind and your place of habitation be with the beasts of the field, and you be given grass to eat like cattle and be drenched with the dew of heaven; and seven periods of time will pass over you, until you know that the Most High is the powerful ruler over the kingdom of mankind and gives it to whomever He wishes.

“He was also driven away from the sons of men, and his heart was made like that of beasts, and his place of habitation was with the wild donkeys. He was given grass to eat like cattle, and his body was drenched with the dew of the sky until he knew that the Most High God is the powerful ruler over the kingdom of mankind and that He sets up over it whomever He wishes.
