Thou, O king, art a king of kings
Having many kings subject and tributary to him, or would have; as the kings of Judah, Ammon, Moab, and others, and who were even his captives and prisoners; see ( Jeremiah 52:32 ) . Jarchi and Saadiah join this with the next clause, "the God of heaven", and interpret it of him thus, thou, O King Nebuchadnezzar, "the King of kings, who is the God of heaven, hath given unto thee"; so some in the Talmud understand it of God F11; but this is contrary to the accents: for the God of heaven hath given thee a kingdom, power, and strength,
and glory;
that is, a very powerful, strong, and glorious kingdom, famous for its mighty armies, strong fortresses, and great riches, from all which the king had great honour and glory; and this he had not by his ancestors, or his own military skill and prowess, but by the favour and gift of God.
