Matthew 1:18-21 (Douay-Rheims 1899 American Edition.)
18Now the generation of Christ was in this wise. When as his mother Mary was espoused to Joseph, before they came together, she was found with child, of the Holy Ghost.
19Whereupon Joseph her husband, being a just man, and not willing publicly to expose her, was minded to put her away privately.
20But while he thought on these things, behold the angel of the Lord appeared to him in his sleep, saying: Joseph, son of David, fear not to take unto thee Mary thy wife, for that which is conceived in her, is of the Holy Ghost.
21And she shall bring forth a son: and thou shalt call his name JESUS. For he shall save his people from their sins.
