16 Then the king commanded, and Daniel was brought and cast into the den of lions. The king declared[1] to Daniel, "May your God, whom you serve continually, deliver you!" 17 And a stone was brought and laid on the mouth of the den, and the king sealed it with his own signet and with the signet of his lords, that nothing might be changed concerning Daniel.
18 Then the king went to his palace and spent the night fasting; no diversions were brought to him, and sleep fled from him.

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.
