It is probably a safe assumption that Passover is most likely to be associated with freedom. As we move through the Seder, we reflect on our ancestors’ fight for freedom and those around the world today who are not free.
What is interesting to me, though, is that the Torah is not translated for the words “freedom” or “free.” Moses does not go before Pharaoh and ask for freedom, rather he asks for his people to be let go. And, I think this is a subtle and important distinction. There is something particular about being released from oppression, compared to assuming the rights to live according to your own beliefs and views. They are hopefully complementary actions.
