Daniel 6:6-11
6 Then these presidents and princes assembled together to the king, and said thus unto him, King Darius, live for ever.

7 All the presidents of the kingdom, the governors, and the princes, the counsellors, and the captains, have consulted together to establish a royal statute, and to make a firm decree, that whosoever shall ask a petition of any God or man for thirty days, save of thee, O king, he shall be cast into the den of lions.

8 Now, O king, establish the decree, and sign the writing, that it be not changed, according to the law of the Medes and Persians, which altereth not.

9 Wherefore king Darius signed the writing and the decree.

10 Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime.

11 Then these men assembled, and found Daniel praying and making supplication before his God.
