'Correct' in the Bible

So they approached the king and said to him, "Did you not issue an edict to the effect that for the next thirty days anyone who prays to any god or human other than to you, O king, would be thrown into a den of lions?" The king replied, "That is correct, according to the law of the Medes and Persians, which cannot be changed."

The vision of the evenings and mornings that was told to you is correct. But you should seal up the vision, for it refers to a time many days from now."
