Daniel 10:1

And Daniel continued until the first year of Cyrus the king.

So this Daniel enjoyed success in the kingdom of Darius and in the kingdom of Cyrus the Persian.

“And what had appeared about the evenings and mornings Which has been told is true; But as for you, conceal the vision, For it pertains to many days in the future.”

“So now I will tell you the truth. Behold, three more kings are going to stand in Persia. Then a fourth will gain far more riches than all of them; as soon as he becomes strong through his riches, he will arouse the whole empire against the kingdom of Greece.
