Here you go, I wrote this myself:
Martin Luther King had latched on to several key rhetorical devices during his public speeches. In his 1963 work, "I Have a Dream," a device he used to convey his message of equality was repetition. Stating that "now is the time" on multiple occasions, he was urging the audience that there was no longer room to wait, and that equality needed to happen immediately. (Citation goes here)
