Consider the following three quotes in connection with the commentary on Beshalach:

1) “…we must dismiss the fallacious notion that white people can give anybody their freedom. No man can give anybody his freedom. A man is born free. You may enslave a man after he is born free, and that is in fact what this country does. It enslaves black people after they’re born, so that the only acts that white people can do is to stop denying black people their freedom; that is, they must stop denying freedom. They never give it to anyone.”^[22]

2) “You get freedom by letting your enemy know that you’ll do anything to get your freedom; then you’ll get it. It’s the only way you’ll get it.”

–Malcolm X, Advice to the Youth of Mississippi (31 December 1964)

3) “Freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.”

— Martin Luther King Jr.,  “Letter from Birmingham Jail,” April 16, 1963
