Daniel 4:25-26

25You will be driven away from people to live with the wild animals. You will feed on grass like cattle and be drenched with dew from the sky for seven periods of time, until you acknowledge that the Most High is ruler over human kingdoms, and he gives them to anyone he wants.

26As for the command to leave the tree’s stump with its roots, your kingdom will be restored to you as soon as you acknowledge that Heaven rules.
