And whence is this to me? - An expression of humility. Why is it that the mother of my Lord should come to me, as if to honor me?
Mother of my Lord - The word “Lord” sometimes denotes “divinity,” and sometimes superior, master, teacher, or governor. It was given by the Jews to their expected Messiah; but whether they understood it as denoting divinity cannot now be ascertained. It is clear only that Elizabeth used it as denoting great dignity and honor.
