In the except, the epistrophe is a repetition of the same word or words at the end of the successive phrases. This is commonly known as epihphora and occasionally as an antistrophe. The technique is used to add rhythm and brings emphasis to the writing. When a word is repeated, it brings more attention and focus to the idea being discussed. Here is an example:
My God bless you. My the good Lord watch over you. May he make his face shine upon you.
