Anaphora is the repetition of a phrase to drive home the impact of a speech. Dr. Martin Luther King, Jr. used anaphora to great effect in several parts of his famous “I have a dream” speech. Here are a few examples:
Now is the time to make real the promise of democracy.

Now it the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice.

Now it the time to lift our nation from the quicksand of racial injustice to the solid rock of brotherhood.

Now is the time to make justice a reality to all of God’s children.

And another:

We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities.

We cannot be satisfied as long as the colored person’s basic mobility is from a smaller ghetto to a larger one.

We can never be satisfied as long as our children are stripped of their selfhood and robbed of their dignity by signs stating “for white only.”

We cannot be satisfied as long as a colored person in Mississippi cannot vote and a colored person in New York believes he has nothing for which to vote.

No, no we are not satisfied and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.

And of course, these ines made this speech one of the most memorable in history:

I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.

I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression will be transformed into an oasis of freedom and justice.

I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today.

I have a dream that one day down in Alabama with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification, one day right down in Alabama little Black boys and Black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today.

I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.

King combines anaphora—I have a dream—with alliteration:

…not by the color of their skin but by the content of their character.
