And the angel came in unto her, and said, Hail, you that are highly favored, the Lord is with you: blessed are you among women.
All Commentaries on Luke 1:28 Go To Luke 1
Ambrose of Milan

But mark the Virgin by her bashfulness, for she was afraid, as it follows; And when she heard, she was troubled. It is the habit of virgins to tremble, and to be ever afraid at the presence of man, and to be shy when he addresses her. Learn, O virgin, to avoid light talking. Mary feared even the salutation of an angel.
She wondered also at the new form of blessing, unheard of before, reserved for Mary alone.
