“For what shall we say? Was Daniel cast into the den of lions by those who feared God? Were Ananias and Azarias and Mishael shut up in a furnace of fire by those who observed the great and glorious worship of the Most High? Far from us be such a thought! Who, then, were they that did such things? The hateful, and those full of all wickedness, were roused to such a pitch of fury that they inflicted torture on those who served God with a holy and blameless purpose [of heart], not knowing that the Most High is the defender and protector of all such as with a pure conscience venerate his all-excellent name.… But they who with confidence endured [these things] are now heirs of glory and honor and have been exalted and made illustrious by God in their memorial for ever and ever.”

“From Syria even unto Rome I fight with beasts, not that I am devoured by brute beasts, for these, as ye know, by the will of God, spared Daniel, but by beasts in the shape of men, in whom the merciless wild beast himself lies hid, and pricks and wounds me day by day. But none of these hardships "move me, neither count I my life dear unto myself," in such a way as to love it better than the Lord. Wherefore I am prepared for [encountering] fire, wild beasts, the sword or the cross, so that only I may see Christ my Saviour and God, who died for me. I therefore, the prisoner of Christ, who am driven along by land and sea, exhort you: "stand fast in the faith," and be ye steadfast, "for the just shall live by faith;" be ye unwavering, for "the Lord causes those to dwell in a house who are of one and the same character."”

“Lord, who fulfilled your promises made by the prophets, and had mercy on Zion and compassion on Jerusalem, by exalting the throne of David, your servant … by the birth of Christ, who was born of his seed according to the flesh, of a virgin alone; please, O Lord God, accept the prayers that proceed from the lips of your people which are of the Gentiles, which call on you in truth, as you accepted the gifts of the righteous in their generations. In the first place you respected the sacrifice of Abel … of Ezra at the return; of Daniel in the den of lions; of Jonah in the whale's belly.”

“Let not, therefore, any one that works signs and wonders judge any one of the faithful who is not granted the same: for the gifts of God that are bestowed by him through Christ are various; and one person receives one gift and another another.… For neither did the wise Daniel, who was delivered from the mouths of the lions, nor the three children, who were delivered from the furnace of fire, despise the rest of their fellow Israelites: for they knew that they had not escaped these terrible miseries by their own might but by the power of God did they both work miracles and were delivered from miseries. Wherefore let none of you exalt himself against his brother, though he is a prophet or though he is a worker of miracles.”

“And a stone was brought, and laid upon the mouth of the den,.... Not a heap of stones, but a single one, a very large one, sufficient to stop up the mouth of the den, that nothing might enter in at it, or be cast into it: this stone was brought by proper persons, and a sufficient number of them, according the order of the king, or his princes, or both; for what Jarchi says, of there being no stones in Babylon, only bricks, and of the angels bringing this stone out of the land of Israel, is all fabulous: but for what end it should be brought and laid is not easy to say; if it was laid here by the order of the princes, it could not surely be to keep any of his friends from going in to deliver him, for who would venture himself there? nor to keep Daniel in it, since it might be concluded, that, as soon as ever he was cast in, he would be seized upon by the lions and devoured at once; unless it can be thought, that these men saw, that when he was thrown in, the lions did not meddle with him; which they might attribute to their having been lately fed, and therefore, that he might be reserved till they were hungry, they did this: if it was by the order of the king, which is very likely, the reason might be, he believed, or at least hoped, that God would deliver him from the lions; but lest his enemies, seeing this, should throw in stones or arrows, and kill him, the mouth of the den was stopped, so Jarchi and Saadiah: no doubt but this was so ordered by the providence of God, as well as the sealing of it, that the miracle of the deliverance might appear the more manifest: and the king sealed it with his own signet, and with the signet of the lords; that none might dare to remove it; so the stone that was laid at the door of Christ's sepulchre was sealed with a seal, Mat 27:66, the reason of sealing it follows, that the purpose might not be changed concerning Daniel: the view the lords had in it was, that the king might not change the sentence passed on Daniel, or take any methods to deliver him; and the view the king had in it might be, that should he be saved from the lions, as he hoped he would, that no other sentence might pass upon him, or he be delivered to any other kind of death.”

“Then the king commanded - With a heavy heart he was obliged to warrant this murderous conspiracy. But when passing sentence his last words were affecting: "Thy God, whom thou servest continually, he will deliver thee." He is thy God; thou servest him, not occasionally, but continually; therefore "he will deliver thee." Daniel had now the same kind of opportunity of showing his fidelity to God, as his three Hebrew companions before. The lions were not less terrible than the fiery furnace.”

“Thy God . . . will deliver thee--The heathen believed in the interposition of the gods at times in favor of their worshippers. Darius recognized Daniel's God as a god, but not the only true God. He had heard of the deliverance of the three youths in Dan 3:26-27 and hence augurs Daniel's deliverance. I am not my own master, and cannot deliver thee, however much I wish it. "Thy God will." Kings are the slaves of their flatterers. Men admire piety to God in others, however disregarding Him themselves.”
