Luke 1:69
He has raised up a horn of salvation for us in the house of his servant David — the horn of salvation (keras sōtērias) is the powerful deliverer of Psalm 18:2 and Hannah's song (1 Samuel 2:10). In the house of his servant David: the Davidic covenant is the specific promise being fulfilled. The raised up (ēgeiren) echoes the resurrection language — the same verb used for God raising up the dead will be used for God raising up the Davidic deliverer.
