Daniel 6:16-17

So, the king gave orders to have Daniel brought in and cast into the lions’ den. But before they threw him into the lions’ den, the king said to Daniel, “Your God, whom you serve so faithfully, he will surely come to rescue you.” A large stone was then brought and placed over the opening of the den, and the king sealed it with his own signet ring and with the signet rings of each of his nobles so that Daniel’s fate might not be changed.
