Here begins the interpretation of the dream: the tree was an emblem of King Nebuchadnezzar, of his greatness, and growing power and strength:for thy greatness is grown, and reacheth unto heaven; he overtopped all the kings of the earth, exceeding them in honour and power, and aspired to deity itself; See Gill on "Da 4:11"and thy dominion to the end of the earth; as far as Hercules's pillars, as Strabo says he came.
Grotius interprets it, as far as the Caspian and Euxine sea, and the Atlantic ocean. Geograph. l. 15. p.
