Daniel 4:32-33

32You will be forced away from people and live with the wild animals. You will eat grass like cattle. And seven time periods will pass until you realize that the Most High has power over human kingdoms and that he gives them to whomever he wishes.”

33Just then the prediction about Nebuchadnezzar came true. He was forced away from people and ate grass like cattle. Dew from the sky made his body wet until his hair grew as long as eagles’ feathers and his nails grew as long as birds’ claws.
