From Dr. Martin Luther King's 1963 "I Have a Dream" Speech at the March on Washington:

"I have a dream today . . .

"This will be the day when all of God’s children will be able to sing with new meaning. “My country, ’tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim’s pride, from every mountain side, let freedom ring.” And if America is to be a great nation, this must become true. So let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania. Let
freedom ring from the snowcapped Rockies of Colorado. Let freedom ring from the curvaceous slopes of
California.

"But not only that. Let freedom ring from Stone Mountain of Georgia. Let freedom ring from Lookout
Mountain of Tennessee. Let freedom ring from every hill and molehill of Mississippi, from every
mountain side. Let freedom ring . . .

"When we allow freedom to ring—when we let it ring from every city and every hamlet, from every state
and every city, we will be able to speed up that day when all of God’s children, black men and white
men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual, “Free at last, Free at last, Great God a-mighty, We are free at last.”
