These is the quote from Rabbi Heschel and Rev King that I reference in the episode:

I solemnly pledge to uphold the fair name of Jews. Not only because we need their friendship, and surely we do, but mainly because bigotry in any for is an affront to us all. (Rev Martin Luther King Jr.)

One hundred years ago, the emancipation was proclaimed. It is time for the white man to strive for self-emancipation, to set himself free of bigotry. (Rabbi Abraham Joshua Heschel)
