Final answer:
Isaiah foretold that Cyrus the Great, the Persian emperor, would be the chosen one of YHWH to enable the exiled Hebrews to return to Jerusalem.
Step-by-step explanation:
In the Book of Isaiah within the Hebrew Bible, the prophet Isaiah foretells that a chosen one of YHWH will enable the remnant of Judah to return to Jerusalem. This figure is known as Cyrus the Great of Persia. Isaiah refers to Cyrus as the 'anointed' one (messiah, in Hebrew) who will be used by YHWH to deliver the Hebrews and facilitate their return. Contrary to Jewish expectations of a messiah coming from their own ranks to liberate them and restore their land, Cyrus, a foreign ruler, was proclaimed by Isaiah as the chosen instrument of divine will to allow the exiled Hebrews to return to their homeland after the Babylonian Captivity. Cyrus indeed accomplished this by conquering Babylon and authorizing the return of the Hebrews to Jerusalem and the rebuilding of their Temple, as documented in the historical records of the time.
