Daniel 6:11

Wherefore king Darius signed the writing and the decree.

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.

Then they came near, and spake before the king concerning the king's decree; Hast thou not signed a decree, that every man that shall ask [a petition] of any God or man within thirty days, save of thee, O king, shall be cast into the den of lions? The king answered and said, The thing [is] true, according to the law of the Medes and Persians, which altereth not.

Then answered they and said before the king, That Daniel, which [is] of the children of the captivity of Judah, regardeth not thee, O king, nor the decree that thou hast signed, but maketh his petition three times a day.
