Best if he tells it in his own words.

⁶⁸Praise be to the Lord, the God of Israel, because he has come and has redeemed his people.
⁶⁹ He has raised up a horn of salvation for us in the house of his servant David
⁷⁰ (as he said through his holy prophets of long ago),
⁷¹ salvation from our enemies and from the hand of all who hate us—
⁷² to show mercy to our fathers and to remember his holy covenant,
⁷³ the oath he swore to our father Abraham:
⁷⁴ to rescue us from the hand of our enemies, and to enable us to serve him without fear
⁷⁵ in holiness and righteousness before him all our days.

⁷⁶And you, my child, will be called a prophet of the Most High; for you will go on before the Lord to prepare the way for him,
⁷⁷ to give his people the knowledge of salvation through the forgiveness of their sins,
⁷⁸ because of the tender mercy of our God, by which the rising sun will come to us from heaven
⁷⁹ to shine on those living in darkness and in the shadow of death, to guide our feet into the path of peace.

Luke 1:68-79 (NIV-UK)
