R. Micha'el Rosenberg on MLK Day: A Mighty Stream

One of the most memorable and impactful lines of the Rev. Dr. Martin Luther King Jr.’s “I Have a Dream Speech” is his invocation of the prophet Amos (5:24): “…No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters, and righteousness like a mighty stream.”  Dr. King introduces the words of the prophet to close a section with the repeated refrain “We cannot be satisfied.”  Each repetition of the phrase describes a different oppression that Black Americans face, reaching its climax with Dr. King’s charge that protest against injustice cannot rest until justice and righteousness are as prevalent and unambiguous as the mighty waters.
