20 Then very early in the morning the king got up and went quickly to the lions' hole. 21 And when he came near the hole where Daniel was, he gave a loud cry of grief; the king made answer and said to Daniel, O Daniel, servant of the living God, is your God, whose servant you are at all times, able to keep you safe from the lions? 22 Then Daniel said to the king, O King, have life for ever. 23 My God has sent his angel to keep the lions' mouths shut, and they have done me no damage: because I was seen to be without sin before him; and further, before you, O King, I have done no wrong.

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.
