Daniel 6:19

And a stone was brought, and laid upon the mouth of the den; and the king sealed it with his own signet, and with the signet of his lords; that the purpose might not be changed concerning Daniel.

Then the king went to his palace, and passed the night fasting: neither were instruments of musick brought before him: and his sleep went from him.

And when he came to the den, he cried with a lamentable voice unto Daniel: [and] 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?

Then said Daniel unto the king, O king, live for ever.
