Commentaries:
Ezra 1:1-2 states that Cyrus issued a decree to free the Jews in the first year of his reign over Babylon. Since Cyrus conquered Babylon on October 12, 539 BC, the first year of this reign was 539-538 BC. God through Isaiah, then, named him at least 143 years earlier. What God did through Cyrus also fulfills a prophecy made through Jeremiah (Jeremiah 25:11-14) sometime during the century following Isaiah's death. Ezra distinctly says that God stirred up the spirit of Cyrus to perform this and that Cyrus claimed that God commanded him. Ezra 1:5 states that God also stirred the spirit of the Jews, Levites, and Benjamites to return to Jerusalem to build the Temple, confirming His sovereignty over the whole affair.
