Thematic Bible: Of the medes, irrevocable

Then the king, when he heard these words, was much distressed [over what he had done] and set his mind on Daniel to deliver him; and he labored until the sun went down to rescue him. Then these same men came thronging [by agreement] to the king and said, Know, O king, that it is a law of the Medes and Persians that no decree or statute which the king establishes may be changed or repealed.
