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.

The Median king is a puppet in his lords' hands; they take the security of their own seal as well as his, that he should not release Daniel. The king's seal guaranteed Daniel from being killed by them, should he escape the lions.
