Daniel 6:26

“I make a decree, that in every dominion of my kingdom, etc.] In every province of his large empire; this explains who are meant by all people, nations, etc. 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:…”

“Stronger than the decree (Dan 3:29). That was negative; this, positive; not merely men must say "nothing amiss of," but must "fear before God."”

“I make a decree - Compare Daniel 3:29. That in every dominion of my kingdom - Every department or province. The entire kingdom or empire was made up of several kingdoms, as Media, Persia, Babylonia, etc. The meaning is, that he wished the God of Daniel to be honored and reverenced throughout the whole empire. Men tremble and fear before the God of Daniel - That they honor and reverence him as God. There is no certain evidence that he meant that he should be honored as the only God; but the probability is, that he meant that he should be recognized as a God of great power and glory, and as worthy of universal reverence. How far this pagan monarch might still regard the other deities…”

“make: Dan 3:29; Ezr 6:8-12, Ezr 7:12, Ezr 7:13 tremble: Psa 2:11, Psa 99:1-3, Psa 119:120; Isa 66:2; Jer 10:10; Luk 12:5; Heb 12:29 for: Dan 4:34; Deu 5:26; Sa1 17:26, Sa1 17:36; Hos 1:10; Act 17:25; Rom 9:26; Th1 1:9; Rev 4:10, Rev 5:14 and stedfast: Psa 93:1, Psa 93:2, Psa 146:10; Mal 3:6; Heb 6:17, Heb 6:18; Jam 1:17 and his kingdom: Dan 2:44, Dan 4:3, Dan 4:34, Dan 7:14, Dan 7:27; Psa 29:10, Psa 145:12, Psa 145:13; Isa 9:7; Mat 6:13; Luk 1:33; Rev 11:15 Daniel 6:27”

“(6:25-27) The consequences of this occurrence. As Nebuchadnezzar, after the wonderful deliverance of Daniel's friends from the burning fiery furnace, issued an edict to all the nations of his kingdom forbidding them on pain of death from doing any injury to these men of God ( Dan 3:29), so now Darius, in consequence of this wonderful preservation of Daniel in the den of lions, gave forth an edict commanding all the nations of his whole kingdom to fear and reverence Daniel's God. But as Nebuchadnezzar by his edict, so also Darius, did not depart from the polytheistic standpoint.
