Hilary of Poitiers, on Matt 2:13

“And after they were departed, behold an angel of the Lord appeared in sleep to Joseph, saying: Arise, and take the child and his mother, and fly into Egypt: and be there until I shall tell thee. For it will come to pass that Herod will seek the child to destroy him.”

“The first time when he would teach Joseph that she was lawfully espoused, the Angel called the Virgin his espoused wife; but after the birth she is only spoken of as the Mother of Jesus. As wedlock was rightfully imputed to her in her virginity, so virginity is esteemed venerable in her as the mother of Jesus.”
