Epanaphora is the repetition of a word (or perhaps words) at the beginning of a series of clauses or phrases:

The Lord sitteth above the water floods.

The Lord remaineth a king for ever.

The Lord shall give strength unto his people.

The Lord shall give his people the blessing of peace.

Psalm 29, quoted in Henry Peachum, The Garden of Eloquence (1593): Schemas. The repetition can be in any form, a question, a declaration, et cetera. The form is pleasant and emphatic. However, Peachum notes that it can easily be misused. First, it can easily be dragged on without purpose and thus become tedious rather than useful. Second, since the form emphasizes the lead word it misleads if the word repeated is not the central concept of the section.
