Daniel 6:12

6:12 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.”

Daniel 11:6

11:6 After some years have passed, they will form an alliance. Then the daughter of the king of the south will come to the king of the north to make an agreement, but she will not retain her power, nor will he continue in his strength. She, together with the one who brought her, her child, and her benefactor will all be delivered over at that time.
