“He has raised up
A mighty savior
In the house
Of his servant David.”
καὶ ἤγειρεν κέρας σωτηρίας ἡμῖν ἐν οἴκῳ Δαυεὶδ παιδὸς αὐτοῦ,
Luke had Zechariah continue with his canticle of praise. Zechariah said that God had raised up a horn of salvation (καὶ ἤγειρεν κέρας σωτηρίας) or a mighty savior for them in the house of his servant David (ἡμῖν ἐν οἴκῳ Δαυεὶδ παιδὸς αὐτοῦ). This was a reference to the savior Jesus rather than to his son John. This horn of salvation was a common theme in the psalms, like in the victory Psalm 18:2, where God was David’s shield, his horn, his stronghold, and his savior. In Psalm 89:17-24 and Psalm 75:5, the psalmist glorified in his strength, since the horn was a symbol of strength. Clearly this strong savior was linked to the house of David.
