Daniel 6:25-29

Then Darius the king wrote to all the peoples, nations, and populations of all languages who were living in all the land: “May your peace be great!

I issue a decree that in all the realm of my kingdom people are to tremble and fear before the God of Daniel; For He is the living God and enduring forever, And His kingdom is one which will not be destroyed, And His dominion will be forever.

“He rescues, saves, and performs signs and miracles In heaven and on earth, He who has also rescued Daniel from the power of the lions.”

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