Daniel 6:12

12 And they went before the king, and spoke concerning the king's decree: "Have you not signed a decree that every man who petitions any god or man within thirty days, except you, 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 does not alter."

Daniel 6:12 Meaning and Commentary

Daniel 6:12

Then they came near
They went immediately from Daniel's house to the king's palace, and into the king's presence; which they could do, either by virtue of their offices, or being admitted by the proper officer in waiting: and spake before the king concerning the king's decree;
at first they said nothing about Daniel, but about the decree, to get it recognized, and afresh ratified and confirmed; lest, under some pretence or another, the king should change it: 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?
they do not say peremptorily that he had signed such a decree, but put the question to him, that they might have it affirmed by himself: the king answered and said, the thing is true, according to the law of
the Medes and Persians, which altereth not;
it is true that such a decree is made and signed, and it is an unalterable one; such as is every established and signed decree of the Medes and Persians: it is as if he had said, it is very true what you put me in mind of, and I will never recede from it, or nullify and make it void.

Daniel 6:12 In-Context

10 Now when Daniel knew that the writing was signed, he went home. And in his upper room, with his windows open toward Jerusalem, he knelt down on his knees three times that day, and prayed and gave thanks before his God, as was his custom since early days.

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

12 And they went before the king, and spoke concerning the king's decree: "Have you not signed a decree that every man who petitions any god or man within thirty days, except you, 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 does not alter."

13 So they answered and said before the king, "That Daniel, who is one of the captives from Judah, does not show due regard for you, O king, or for the decree that you have signed, but makes his petition three times a day."

14 And the king, when he heard these words, was greatly displeased with himself, and set his heart on Daniel to deliver him; and he labored till the going down of the sun to deliver him.
