Catena Aurea · Lukasevangelium 2
And Joseph and his mother marvelled at those things which were spoken of him. And Simeon blessed them, and said unto Mary his mother, Behold, this child is set for the fall and rising again of many in Israel; and for a sign which shall be spoken against; (Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.
Or it shews the wisdom of Mary, that she was not ignorant of the heavenly Majesty. For the word of God is living and strong, and sharper than the sharpest sword. (Heb. 4:12.)
