I make a decree, that in every dominion of my kingdom,.... In every province of his large empire; this explains who are meant by all people, nations, &c. before mentioned; namely, such as were within his dominions; for to no other could his decree reach: this decree is very different from that he had made a few days before, forbidding any man to ask anything of any god or man for the space of a month; but now his order is, that men tremble and fear before the God of Daniel; that they would serve with fear and trembling, and reverence and adore the God that Daniel served and worshipped; and who manifestly appeared to be his God, and to be the true God, by his wonderful deliverance of him: for he is the living God, and steadfast for ever; that has life in himself, and is the author and giver of life to others, and ever remains so, without any variation or shadow of turning; he is everlasting and unchangeable, permanent and immutable in his nature; steady and steadfast in his purposes and promises, in his conduct in the government of the world, and in the course of his providence: and his kingdom that which shall not be destroyed, and his dominion shall be even unto the end; unto the end of time; other kingdoms will he destroyed, but his will not; all other rule, dominion and authority will be at an end but his will continue for ever; his kingdom is an everlasting one: this doctrine Darius had learned from Daniel, as Nebuchadnezzar before had done; see Dan 2:44.
