“A great sense of mission guides us. A great sense of mission guides me. I act day and night in your name, on your behalf, on behalf of our country, on behalf of our people, on behalf of our land!”

2013, Eulogy of Nelson Mandela (December 2013)
Context: The struggles that follow the victory of formal equality or universal franchise may not be as filled with drama and moral clarity as those that came before, but they are no less important. For around the world today, we still see children suffering from hunger and disease. We still see run-down schools. We still see young people without prospects for the future. Around the world today, men and women are still imprisoned for their political beliefs, and are still persecuted for what they look like, and how they worship, and who they love. That is happening today. And so we, too, must act on behalf of justice. We, too, must act on behalf of peace. There are too many people who happily embrace Madiba’s legacy of racial reconciliation, but passionately resist even modest reforms that would challenge chronic poverty and growing inequality. There are too many leaders who claim solidarity with Madiba’s struggle for freedom, but do not tolerate dissent from their own people. And there are too many of us on the sidelines, comfortable in complacency or cynicism when our voices must be heard.

This has commonly been attributed to Orwell but has not been found in any of his writings. Quote Investigator http://quoteinvestigator.com/2011/11/07/rough-men/ found the earliest known appearance in a 1993 Washington Times essay by Richard Grenier: "As George Orwell pointed out, people sleep peacefully in their beds at night only because rough men stand ready to do violence on their behalf." The absence of quotation marks indicates Grenier was using his own words to convey Orwell's opinion; thus it may have originated as a paraphrase of his statement in "Notes on Nationalism" https://www.mtholyoke.edu/acad/intrel/orwelnat.htm (May 1945): "Those who "abjure" violence can only do so because others are committing violence on their behalf." There are also similar sentiments expressed in an essay which Orwell wrote on Rudyard Kipling, quoting from one of Kipling's poems: "Yes, making mock o' uniforms that guard you while you sleep." In the same essay Orwell also wrote of Kipling: "He sees clearly that men can only be highly civilized while other men, inevitably less civilized, are there to guard and feed them."

Context: In the US we can buy comfort or clean water as needed. In India they cannot even when they do have the money as the country right now is going through a terrible drought as they are in other places around the world such as Australia as I understand it. We are a bit spoiled here no matter how much money we have or don't have.
I really hope people will enjoy seeing "Manuel Rivera-Ortiz: India" there at El Museo. I really hope that those that do feel comfortable and free to contact me and share their stories, ideas or suggestions, do. I too do not ever pretend operate in a vacuum. This work is done on all of our behalf.

On the benefits of emigration of intelligent and skilled workers from India to other nations, as quoted in "Return Passage to India: Emigres Pay Back" by Celia W. Dugger, in The New York Times (29 February 2000) http://www.nytimes.com/2000/02/29/world/return-passage-to-india-emigres-pay-back.html?pagewanted=all; also cited in: Kishore Mahbubani, The New Asian Hemisphere: The Irresistible Shift of Global Power to the East https://books.google.nl/books?id=3bNEcyRxk3oC&pg=PA69&lpg=PA69&dq=charles+leadbeater++%22from+west+to+east%22&source=bl&ots=5P_cDPHVZF&sig=GfkXHeh-xNDhko5-h2NqD67zP5E&hl=nl&sa=X&ved=0ahUKEwjF_afS-qzLAhXHzxQKHUcKBEoQ6AEIKDAB#v=onepage&q=Bhagwati&f=false (2010), p. 71
Context: The emigres often work as a Trojan horse, lobbying on your behalf. They use external opportunities to succeed prodigiously in different occupations. And they can bring their skills and funds home to assist the country in its economic takeoff.

Introduction
Free Culture (2004)
Context: I believe it would be right for common sense to revolt against the extreme claims made today on behalf of "intellectual property." What the law demands today is increasingly as silly as a sheriff arresting an airplane for trespass. But the consequences of this silliness will be much more profound.
