Luke 1: 69 - 75
69 and has raised up a horn of salvation for us in the house of his servant David,
70 as he spoke by the mouth of his holy prophets from of old,
71 that we should be saved from our enemies, and from the hand of all who hate us;
72 to perform the mercy promised to our fathers, and to remember his holy covenant,
73 the oath which he swore to our father Abraham,
74 to grant us that we, being delivered from the hand of our enemies, might serve him without fear,
75 in holiness and righteousness before him all the days of our life.
