And hath raised up an horn of salvation for us,.... Meaning the Messiah, whom God had now raised up: in the house of his servant David; in David's family, he being now conceived by a virgin of his house; and who, in a little time, would be born in Bethlehem, the city of David. He is called "an horn of salvation", because he is a powerful Saviour.
