DAN 4:33

33 Immediately what [God] predicted happened. Nebuchadnezzar [became insane, so his advisors] forced him to live away from other people. He ate grass like cows [do], and dew from the sky caused his body to be damp/wet [every morning. He lived like that] until his hair was as long as eagles’ feathers, and his fingernails became like birds’ claws.
