Augustine of Hippo

(de Nov. ac vet, Test. c. 73.) Or by this is signified that Mary also, through whom was performed the mystery of the incarnation, looked with doubt and astonishment at the death of her Lord, seeing the Son of God so humbled as to come down even to death. And as a sword passing close by a man causes fear, though it does not strike him; so doubt also causes sorrow, yet does not kill; for it is not fastened to the mind, but passes through it as through a shadow.
