Mateus 1:20-25 - Bíblia Online

But while he thought on these things, the angel of the Lord appeared to him in a dream, saying, Joseph, thou son of David, fear not to take to thee Mary thy wife: for that which is conceived in her is by the Holy Spirit. 
And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins. 
Now all this was done, that it might be fulfilled which was spoken from the Lord by the prophet, saying, 
Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us. 
Then Joseph, being raised from sleep, did as the angel of the Lord had bidden him, and took to him his wife: 
And knew her not till she had brought forth her first-born son: and he called his name JESUS.
