Thus saith Cyrus king of Persia: All the kingdoms of the earth hath the LORD, the God of heaven, given me; and He hath charged me to build Him a house in Jerusalem, which is in Judah. Whosoever there is among you of all His people--the LORD his God be with him--let him go up.

—2 Chronicles 36:23 (JPS)

Here, Cyrus seems to believe that God (the god of the Jews) has the power to give him all kingdom in the earth. Does Cyrus in fact believe in God?
