Cyrus's decision to free captive peoples held in Babylon, including the deported Judeans, was likely a calculated political move to win favor across his new empire, but its consequences—including being named 'Messiah' in Hebrew scripture—far exceeded anything he could have anticipated.

91:59Like the people of Babylon with Marduk, the  Judeans interpreted Cyrus as having been chosen by their god Yahweh to set them free.  Cyrus might have calculated that sending back these few thousand deportees would improve  his reputation around his new empire, but he couldn't have predicted quite how long  or how far this act of kindness would be remembered. Since the Hebrew Bible would form  the basis for the future Christian religion,

92:30his good deed would be immortalized in the holy  text of one of the world's major religions. The Hebrew poet prophet we know as Second Isaiah  would even go so far as to name Cyrus with a title that in Hebrew was pronounced ‘mashiach’,  which meant ‘the anointed one of God’, a title which gives us the English word ‘messiah’. This  is what the Lord says to Cyrus, his Messiah,

93:02whose right hand he will empower. Before  him, mighty kings will be paralyzed with fear. Their fortress gates will be opened, never  to shut again. Cyrus would be the first and only non-Jewish person to ever be awarded that title,  a testament to his skill at winning people over. Meanwhile, the name Babylon would pass into  memory as a byword for oppression, slavery, and corruption, a reminder that our actions in history  can resonate far longer than we might ever expect.
