As a Jew very much devoted to my religion, I take the Passover story very seriously. That said, there is one part of the narrative that I feel speaks more to my political side than my religious. It concerns the loss of freedom, rather than the obtaining of it.
To many, the Passover story begins with the ancient Israelites already enslaved in Egypt. Another way to approach the Passover story is to consider its beginning when Joseph invited his brothers and their families to relocate in Goshen, Egypt, (hundreds of years earlier).
Just to backtrack for a moment, as you no doubt recall, Joseph's brothers, who once sold Joseph into slavery and presumed him long dead, had come to Egypt seeking relief from the drought. Joseph recognized them but they did not recognize him. After testing them a bit to see if they had grown morally, he eventually revealed himself to them, and, bearing no malice, invited his siblings and their families to move to Goshen where he could help them beat the remainder of the seven-year drought, and, as the number two man of Egypt, be able to look after their well-being in general.
