20 and at his coming near to the den, to Daniel, with a grieved voice, he crieth. The king hath answered and said to Daniel, O Daniel, servant of the living God, thy God, whom thou art serving continually, is He able to deliver thee from the lions?' 21 Then Daniel hath spoken with the king: 'O king, to the ages live: 22 my God hath sent His messenger, and hath shut the lions' mouths, and they have not injured me: because that before Him purity hath been found in me; and also before thee, O king, injury I have not done.' 23 Then was the king very glad for him, and he hath commanded Daniel to be taken up out of the den, and Daniel hath been taken up out of the den, and no injury hath been found in him, because he hath believed 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.
