Daniel 6:16-28
Then the king commanded, and Daniel was brought and cast into the den of lions. The king said to Daniel, "May your God, whom you serve continually, deliver you!" 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 nothing might be changed concerning Daniel.
Then the king went to his palace, and spent the night fasting; no diversions were brought to him, and sleep fled from him. Then, at break of day, the king arose and went in haste to the den of lions. When he came near to the den where Daniel was, he cried out in a tone of anguish and said to Daniel, "O Daniel, servant of the living God, has your God, whom you serve continually, been able to deliver you from the lions?"
Then Daniel said to the king, "O king, live for ever! My God sent his angel and shut the lions' mouths, and they have not hurt me, because I was found blameless before him; and also before you, O king, I have done no wrong."
Then the king was exceedingly glad, and commanded that Daniel be taken up out of the den. So Daniel was taken up out of the den, and no kind of hurt was found upon him, because he had trusted in his God.
And the king commanded, and those men who had accused Daniel were brought and cast into the den of lions -- they, their children, and their wives; and before they reached the bottom of the den the lions overpowered them and broke all their bones in pieces.
Then King Darius wrote to all the peoples, nations, and languages that dwell in all the earth: "Peace be multiplied to you. I make a decree, that in all my royal dominion men tremble and fear before the God of Daniel, for he is the living God, enduring for ever; his kingdom shall never be destroyed, and his dominion shall be to the end. He delivers and rescues, he works signs and wonders in heaven and on earth, he who has saved Daniel from the power of the lions."
So this Daniel prospered during the reign of Darius and the reign of Cyrus the Persian.
