Daniel 4:15-16, 32

Nevertheless leave the stump of its roots in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be wet with the dew of heaven: and let his portion be with the beasts in the grass of the earth: let his heart be changed from man’s, and let a beast’s heart be given unto him; and let seven times pass over him.

and thou shalt be driven from men; and thy dwelling shall be with the beasts of the field; thou shalt be made to eat grass as oxen; and seven times shall pass over thee; until thou know that the Most High ruleth in the kingdom of men, and giveth it to whomsoever he will.
