How did Cyrus become ''liberal-minded''? (THEORY)
According to Histories | Book 1 by Herodotus
'' Astyages is plagued with visions that the child of Cambyses will rule Asia. Thus when the child, Cyrus, is born, he orders the child killed. Harpagus, the official who is tasked with the murder, secretly refuses. Instead, he gives the child to a shepherd to raise in secret. Cyrus's talents show through, even at a young age. Among other signs of his greatness, Cyrus plays a game in which the other village children crown him king. Cyrus is soon revealed to be alive, and Harpagus suffers a cruel punishment for his disobedience.''

'Prophecy' begins at Isaiah 44:28 (NKJV):
‘Who says of Cyrus, 'He is My shepherd, And he shall perform all My pleasure, Saying to Jerusalem, "You shall be built," And to the temple, "Your foundation shall be laid."
Abraham, the father of the jews was a 'shepherd', so was Moses and David.. All ''great'' figures of the jews were 'shepherds'.
There's also a reference to 'shepherds of Israel' in the bible.
Could the shepherd that raised Cyrus been a jew? Possibly.
