@jamie_blumberg I was thinking of Frederick Douglass' 1859 note that has the phrase "no peace without justice".
MLK later said, "There can be no justice without peace. And there can be no peace without justice." He also said other variants of it and others have said even more variants.
Even the Talmud over a thousand years ago said, "Rabban Simeon b. Gamaliel used to say: By three things does the world endure: justice, truth and peace. R. Muna said: The three are one, because if justice is done, truth has been effected and peace brought about; and all three are mentioned in one verse, as it is stated, Execute the judgment of truth and peace in your gates, [indicating that] wherever justice is done peace is to be found."
I thought I had uploaded the Frederick Douglass note and didn't realize it didn't get uploaded until much later (and then didn't want to edit the post since it would then alert so many people)
