The Genealogy of Jesus the Messiah
20But when he thought on these things, behold, an 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 Spirit. 21And she shall bring forth a son; and thou shalt call his name JESUS; for it is he that shall save his people from their sins. 22Now all this is come to pass, that it might be fulfilled which was spoken by the Lord through the prophet, saying, 23Behold, the virgin shall be with child, and shall bring forth a son, And they shall call his name Immanuel; which is, being interpreted, God with us.
Matthew 1:20-23 (ASV)
