Daniel 4:24-26

this is the interpretation, O king: It is the decree of the Most High [God], which has come upon my lord the king: that you shall be driven from mankind and your dwelling place shall be with the beasts of the field; and that you be given grass to eat like the cattle and be wet with the dew of heaven; and seven periods of time shall pass over you, until you know [without any doubt] that the Most High [God] rules over the kingdom of mankind and He bestows it to whomever He desires. And in that it was commanded to leave the stump with the roots of the tree [in the earth], your kingdom shall be restored to you after you recognize (understand fully) that Heaven rules.
