Anaphora is the repetition of the same word or phrase at the beginning of successive phrases or clauses. It is often used to create a rhythmic effect, or to highlight the importance of a concept. As one of the oldest poetic devices, it is a common feature in devotional and religious poetry, and is found in many Psalms.
|“|| The floods have lifted up, O LORD, the floods have lifted up their voice; the floods lift up their waves.
-- Psalm 93:3
Another excellent example can be found in Shakespeare's Richard II:
|“|| This royal throne of kings, this sceptred isle, |
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by Nature for herself
Against infection and the hand of war.
