Darius here studies to make some amends for the dishonour he had done both to God and Daniel, in casting Daniel into the lions' den, by doing honour to both.
I. He gives honour to God by a decree published to all nations, by which they are required to fear before him. And this is a decree which is indeed fit to be made unalterable, according to the laws of the Medes and Persians, for it is the everlasting gospel, preached to those that dwell on the earth, Rev 14:7. Fear God, and give glory to him. Observe, 1. To whom he sends this decree - to all people, nations and languages, that dwell in all the earth, Dan 6:25. These are great words, and it is true that all the inhabitants of the earth are obliged to that which is here decreed; but here they mean no more than every dominion of his kingdom, which, though it contained many nations, did not contain all nations; but so it is, those that have much are ready to think they have all. 2. What the matter of the decree is - that men tremble and fear before the God of Daniel. This goes further than Nebuchadnezzar's decree upon a similar occasion, for that only restrained people from speaking amiss of this God, but this requires them to fear before him, to keep up and express awful reverent thoughts of him. And well might this decree he prefaced, as it is, with Peace be multiplied unto you, for the only foundation of true and abundant peace is laid in the fear of God, for that is true wisdom. If we live in the fear of God, and walk according to that rule, peace shall be upon us, peace shall be multiplied to us. But, though this decree goes far, it does not go far enough; had he done right, and come up to his present convictions, he would have commanded all men not only to tremble and fear before this God, but to love him and trust in him, to forsake the service of their idols, and to worship him only, and call upon him as Daniel did. But idolatry had been so long and so deeply rooted that it was not to be extirpated by the edicts of princes, nor by any power less than that which went along with the glorious gospel of Christ. 3. What are the causes and considerations moving him to make this decree. They are sufficient to have justified a decree for the total suppression of idolatry, much more will they serve to support this. There is good reason why all men should fear before this God, for, (1.) His being is transcendent. "He is the living God, lives as a God, whereas the gods we worship are dead things, have not so much as an animal life." (2.) His government is incontestable. He has a kingdom, and a dominion; he not only lives, but reigns as an absolute sovereign. (3.) Both his being and his government are unchangeable. He is himself stedfast for ever, and with him is no shadow of turning. And his kingdom too is that which shall not be destroyed by any external force, nor has his dominion any thing in itself that threatens a decay or tends towards it, and therefore it shall be even to the end. (4.) He has an ability sufficient to support such an authority, Dan 6:27. He delivers his faithful servants from trouble and rescues them out of trouble; he works signs and wonders, quite above the utmost power of nature to effect, both in heaven and on earth, by which it appears that he is sovereign Lord of both. (5.) He has given a fresh proof of all this in delivering his servant Daniel from the power of the lions. This miracle, and that of the delivering of the three children, were wrought in the eyes of the world, were seen, published, and attested by two of the greatest monarchs that ever were, and were illustrious confirmations of the first principles of religion, abstracted from the narrow scheme of Judaism, effectual confutations of all the errors of heathenism, and very proper preparations for pure catholic Christianity.
II. He puts honour upon Daniel (Dan 6:28): So this Daniel prospered. See how God brought to him good out of evil. This bold stroke which his enemies made at his life was a happy occasion of taking them off, and their children too, who otherwise would still have stood in the way of his preferment, and have been upon all occasions vexatious to him; and now he prospered more than ever, was more in favour with his prince and in reputation with the people, which gave him a great opportunity of doing good to his brethren. Thus out of the eater (and that was a lion too) comes forth meat, and out of the strong sweetness.

I make a decree that - men tremble and fear before the God of Daniel - As in the case of the three Hebrews, Dan 3:29. The true God was known by his servants, and by the deliverances he wrought for them. See his characters in this decree.
1. He is the living God, the Author and Giver of life; all others are dead gods.
2. He is steadfast for ever. All things change; but he is unchangeable.
3. He has a kingdom; for as he made all things, so he governs all things.
4. His kingdom shall not be destroyed. No human power can prevail against it, because it is upheld by his omnipotence.
5. His dominion is without end. It is an everlasting dominion, under an everlasting rule, by an everlasting God.
6. He delivereth them that are in danger and bondage.
7. He rescueth those who have fallen into the hands of their enemies, and implore his succor.
8. He worketh signs in the heavens.
9. And wonders upon earth; showing that both are under his sway, and are parts of his dominion.
10. And to complete all, He hath delivered Daniel. Before our own eyes he has given the fullest proof of his power and goodness, in rescuing his faithful servant from the teeth of the lions. What a fine eulogium on the great God and his faithful servant!

He delivereth and rescueth..... As he did the three companions of Daniel from the fiery furnace, and now Daniel himself from the lions' den:

and he worketh signs and wonders in heaven and in earth; which are out of the common course of nature, and not according to the laws of it; such as hindering the natural force of fire from burning, as in the case of the three children; and stopping the mouths of lions from devouring Daniel as follows:

who hath delivered Daniel from the power of the lions; or "from the hand" (r) of them; from their destroying paws, and devouring jaws; which was nothing less than a miracle, and a proof of the divine omnipotence and of his power of doing wonders.

(r) "de manu", Montanus, Cocceius.

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."
