Matthew 1:20-23
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.e
21And she shall bring forth a son: and thou shalt call his name JESUS. For he shall save his people from their sins.f
22Now all this was done that it might be fulfilled which the Lord spoke by the prophet, saying:g
23Behold a virgin shall be with child, and bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.h
