26 I make a decree, That in every dominion of my kingdom men tremble and fear before the God of Daniel: for he is the living God, and stedfast for ever, and his kingdom that which shall not be destroyed, and his dominion shall be even unto the end.
Verses 25-27. "Then king Darius wrote unto all the peoples, tribes and language-groups who dwelt in all the earth, saying: 'Your peace be multiplied! I have enacted a decree that in all my empire and kingdom men are to dread and tremble before the God of Daniel. For it is He who is the living God and the One who abides forever, and His rule shall not be overthown, and His power shall eternally endure. It is He who is the Deliverer and Savior, who performs signs and wonders in heaven and on earth, and who has delivered Daniel from the pit of lions.'" Just as in the case of Nebuchadnezzar's writing unto the language-groups and nations one authority has interpreted them to signify hostile powers, so also this same man interprets the action of Darius, on the ground that he summons them all to repentance. And he poses the question as to whether this will take place in this world or in the other world, or even after other worlds have intervened. We deem these speculations to be absurd and account them as empty fables, and make this single observation: that the reason why signs are performed amid barbarian peoples through the agency of God's servants is that the worship and religion of the only God may be proclaimed.
The foundation and strength of hope and faith is fear. In Psalm 111: “The fear of the Lord is the beginning of wisdom.” Of the same thing in the Wisdom of Solomon, … in the Proverbs, … in Isaiah, … in Genesis, … and in Psalm 2, … Then Darius the king wrote, “To all peoples, tribes and languages that are in my kingdom, peace be to you from my face. I decree and ordain that all those who are in my kingdom shall fear and tremble before the Most High God whom Daniel serves.”
[AD 420] Jerome on Daniel 6:25-27
