a horn of salvation
Psalm 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.
3 I will call upon the Lord, who is worthy to be praised: so shall I be saved from mine enemies.
Luke 1:69 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;
