10 Now when Daniel knew that the writing was signed, he went home. And in his upper room, with his windows open toward Jerusalem, he knelt down on his knees three times that day, and prayed and gave thanks before his God, as was his custom since early days.

11 Then these men assembled and found Daniel praying and making supplication before his God. 12 And they went before the king, and spoke concerning the king's decree: "Have you not signed a decree that every man who petitions any god or man within thirty days, except you, O king, shall be cast into the den of lions?" The king answered and said, "The thing is true, according to the law of the Medes and Persians, which does not alter." 13 So they answered and said before the king, "That Daniel, who is one of the captives from Judah, does not show due regard for you, O king, or for the decree that you have signed, but makes his petition three times a day." 14 And the king, when he heard these words, was greatly displeased with himself, and set his heart on Daniel to deliver him; and he labored till the going down of the sun to deliver him. 15 Then these men approached the king, and said to the king, "Know, O king, that it is the law of the Medes and Persians that no decree or statute which the king establishes may be changed." 16 So the king gave the command, and they brought Daniel and cast him into the den of lions. But the king spoke, saying to Daniel, "Your God, whom you serve continually, He will deliver you." 17 Then a stone was brought and laid on the mouth of the den, and the king sealed it with his own signet ring and with the signets of his lords, that the purpose concerning Daniel might not be changed.

18 Now the king went to his palace and spent the night fasting; and no musicians were brought before him. Also his sleep went from him. 19 Then the king arose very early in the morning and went in haste to the den of lions. 20 And when he came to the den, he cried out with a lamenting voice to Daniel. The king spoke, saying to Daniel, "Daniel, servant of the living God, has your God, whom you serve continually, been able to deliver you from the lions?" 21 Then Daniel said to the king, "O king, live forever! 22 My God sent His angel and shut the lions' mouths, so that they have not hurt me, because I was found innocent before Him; and also, O king, I have done no wrong before you." 23 Then the king was exceedingly glad for him, and commanded that they should take Daniel up out of the den. So Daniel was taken up out of the den, and no injury whatever was found on him, because he believed in his God.

Commentary on Daniel 6:6-10

(Read Daniel 6:6-10)

To forbid prayer for thirty days, is, for so long, to rob God of all the tribute he has from man, and to rob man of all the comfort he has in God. Does not every man's heart direct him, when in want or distress, to call upon God? We could not live a day without God; and can men live thirty days without prayer? Yet it is to be feared that those who, without any decree forbidding them, present no hearty, serious petitions to God for more than thirty days together, are far more numerous than those who serve him continually, with humble, thankful hearts. Persecuting laws are always made on false pretences; but it does not become Christians to make bitter complaints, or to indulge in revilings. It is good to have hours for prayer. Daniel prayed openly and avowedly; and though a man of vast business, he did not think that would excuse him from daily exercises of devotion. How inexcusable are those who have but little to do in the world, yet will not do thus much for their souls! In trying times we must take heed, lest, under pretence of discretion, we are guilty of cowardice in the cause of God. All who throw away their souls, as those certainly do that live without prayer, even if it be to save their lives, at the end will be found to be fools. Nor did Daniel only pray, and not give thanks, cutting off some part of the service to make the time of danger shorter; but he performed the whole. In a word, the duty of prayer is founded upon the sufficiency of God as an almighty Creator and Redeemer, and upon our wants as sinful creatures. To Christ we must turn our eyes. Thither let the Christian look, thither let him pray, in this land of his captivity.

Commentary on Daniel 6:11-17

(Read Daniel 6:11-17)

It is no new thing for what is done faithfully, in conscience toward God, to be misrepresented as done obstinately, and in contempt of the civil powers. Through want of due thought, we often do that which afterwards, like Darius, we see cause a thousand times to wish undone again. Daniel, that venerable man, is brought as the vilest of malefactors, and is thrown into the den of lions, to be devoured, only for worshipping his God. No doubt the placing the stone was ordered by the providence of God, that the miracle of Daniel's deliverance might appear more plain; and the king sealed it with his own signet, probably lest Daniel's enemies should kill him. Let us commit our lives and souls unto God, in well-doing. We cannot place full confidence even in men whom we faithfully serve; but believers may, in all cases, be sure of the Divine favour and consolation.

Commentary on Daniel 6:18-24

(Read Daniel 6:18-24)

The best way to have a good night, is to keep a good conscience. We are sure of what the king doubted, that the servants of the living God have a Master well able to protect them. See the power of God over the fiercest creatures, and believe his power to restrain the roaring lion that goeth about continually seeking to devour. Daniel was kept perfectly safe, because he believed in his God. Those who boldly and cheerfully trust in God to protect them in the way of duty, shall always find him a present help. Thus the righteous is delivered out of trouble, and the wicked cometh in his stead. The short triumph of the wicked will end in their ruin.
