20 And when he came near unto the den to Daniel, he cried with a lamentable voice; the king spake and said to Daniel, O Daniel, servant of the living God, is thy God, whom thou servest continually, able to deliver thee from the lions? 21 Then said Daniel unto the king, O king, live for ever. 22 My God hath sent his angel, and hath shut the lions' mouths, and they have not hurt me; forasmuch as before him innocency was found in me; and also before thee, O king, have I done no hurt. 23 Then was the king exceeding glad, and commanded that they should take Daniel up out of the den. So Daniel was taken up out of the den, and no manner of hurt was found upon him, because he had trusted in his God.

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.
