Pseudo-Augustine
Catena Aurea · Matthäusevangelium 1
But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
(Serm. in App. 195.) Yet though Joseph think on these things, let not Mary the daughter of David be troubled; as the word of the Prophet brought pardon to David, so the Angel of the Saviour delivers Mary. Behold, again appears Gabriel the bridesman of this Virgin; as it follows, Behold the Angel of the Lord appeared to Joseph.
