Luke 2:34-35

34 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;
35 (Yea, a sword shall pierce through thy own soul also,) that the thoughts of many hearts may be revealed.

This is a word given to Mary in the Christmas Narrative, and Simeon blesses Mary by saying the child is set for the fall and rising of many in Israel. What that means, is they fall and  sin unto death, but then rise and come up with Salvation. But many shall speak against this sign. And it shall be a sword that shall pierce through Mary's own soul. And also ours, we shall be divided, but our sin cut off like through a circumcision knife. And whatever the true thoughts of man are, they will appear when the true Gospel is being preached. And whatever their reaction, that is the thoughts and intents of a man's truest heart. So if a savor unto death, it is death, and if vile the heart of man is vile. But, if blessed, and not blasphemous, it is a light in the soul and a lamp to the feet.
