Daniel 6:8-15

8 Now, O king, issue the decree and put it in writing so that it cannot be altered—in accordance with the laws of the Medes and Persians, which cannot be repealed.”

9 So King Darius put the decree in writing.

10 Now when Daniel learned that the decree had been published, he went home to his upstairs room where the windows opened toward Jerusalem. Three times a day he got down on his knees and prayed, giving thanks to his God, just as he had done before.

11 Then these men went as a group and found Daniel praying and asking God for help.

12 So they went to the king and spoke to him about his royal decree: “Did you not publish a decree that during the next thirty days anyone who prays to any god or man except to you, O king, would be thrown into the lions’ den?”
The king answered, “The decree stands—in accordance with the laws of the Medes and Persians, which cannot be repealed.”

13 Then they said to the king, “Daniel, who is one of the exiles from Judah, pays no attention to you, O king, or to the decree you put in writing. He still prays three times a day.”

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

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