Daniel 4:25

that they, the subject being purposely indefinite, shall drive thee from men, casting him out from the society of human beings, and thy dwelling shall be with the beasts of the field, entirely on a level with unreasonable brutes, and they shall make thee to eat grass as oxen, and they shall wet thee with the dew of heaven; and seven times, definite periods of time, shall pass over thee, till thou know, recognizing and acknowledging openly and freely, that the Most High ruleth in the kingdom of men, as the real Sovereign of the several nations of the earth, and giveth it to whomsoever He will. Nebuchadnezzar would, in other words, be seized with madness, which would exclude him from human society for some time, the purpose of the Lord in thus punishing him being to bring him to a realization of his utter helplessness before the true Ruler of the universe.
