Daniel 6:12

12 then they have come near, yea, they are saying before the king concerning the king's interdict: `Hast thou not signed an interdict, that any man who seeketh from any god and man until thirty days, save of thee, O king, is cast into a den of lions?' Answered hath the king, and said, `The thing [is] certain as a law of Media and Persia, that doth not pass away.'

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 And Daniel, when he hath known that the writing is signed, hath gone up to his house, and the window being opened for him, in his upper chamber, over-against Jerusalem, three times in a day he is kneeling on his knees, and praying, and confessing before his God, because that he was doing [it] before this.
11 Then these men have assembled, and found Daniel praying and entreating grace before his God;
12 then they have come near, yea, they are saying before the king concerning the king's interdict: `Hast thou not signed an interdict, that any man who seeketh from any god and man until thirty days, save of thee, O king, is cast into a den of lions?' Answered hath the king, and said, `The thing [is] certain as a law of Media and Persia, that doth not pass away.'
13 Then they have answered, yea, they are saying before the king, that, `Daniel, who [is] of the sons of the Removed of Judah, hath not placed on thee, O king, [any] regard, nor on the interdict that thou hast signed, and three times in a day he is seeking his petition.'
14 Then the king, when he hath heard the matter, is greatly displeased at himself, and on Daniel he hath set the heart to deliver him, and till the going up of the sun he was arranging to deliver him.
