To Remember His Holy Covenant

"Blessed be the Lord God of Israel,
for he has visited and redeemed his people
and has raised up a horn of salvation for us
in the house of his servant David...
to show the mercy promised to our fathers
and to remember his holy covenant,
the oath that he swore to our father Abraham, to grant us
that we, being delivered from the hand of our enemies,
might serve him without fear,
in holiness and righteousness before him all our days."
(Luke 1:68–69, 72-75)
