Matthew 1:18-25

18Now the birth of Jesus Christ was on this wise: When his mother Mary had been betrothed to Joseph, before they came together she was found with child of the Holy Spirit. 19And Joseph her husband, being a righteous man, and not willing to make her a public example, was minded to put her away privily. 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,

which is, being interpreted, God with us. 24And Joseph arose from his sleep, and did as the angel of the Lord commanded him, and took unto him his wife; 25and knew her not till she had brought forth a son: and he called his name JESUS.
