Daniel 4:25-26

25People will chase you away from the city, so that you have to live with the wild animals. You will eat grass like cows do. Dew from the sky will make you wet. You will live in that way for seven years. Then you will understand that the powerful God above rules over human kingdoms. He gives authority to rule to anyone that he chooses.

26The command was to leave the base of the tree and its roots in the ground. This means that you will be king again later. But before that, you will have to understand that it is God in heaven who rules.
