Daniel 6:14-17

14When the king heard this, he was greatly distressed; he was determined to rescue Daniel and made every effort until sundown to save him.

15Then the men went as a group to King Darius and said to him, “Remember, Your Majesty, that according to the law of the Medes and Persians no decree or edict that the king issues can be changed.”

16So the king gave the order, and they brought Daniel and threw him into the lions’ den. The king said to Daniel, “May your God, whom you serve continually, rescue you!” 17A stone was brought and placed over the mouth of the den, and the king sealed it with his own signet ring and with the rings of his nobles, so that Daniel’s situation might not be changed.
