Lk 1:68-71

God is the power of salvation. (Psalms 18:2)

Psalms 18:2 The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower.

God raised up Christ, the power of salvation, from the house of David. That is Jesus. (Luke 1:68-71, Matthew 1:16)

Luke 1:68 Blessed be the Lord God of Israel; for he hath visited and redeemed his people, 69 And hath raised up an horn of salvation for us in the house of his servant David; 70 As he spake by the mouth of his holy prophets, which have been since the world began: 71 That we should be saved from our enemies, and from the hand of all that hate us;

Matthew 1:16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.
