The book of the generation of
the son of David, the son of Abraham.
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Joseph her husband being a just man and not willing to make her a publick example was minded to put her away privily.
But while he thought on these things, behold, the 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 Ghost.
And she shall bring forth 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 of 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 - "God with us"
Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
And knew her not till she had brought forth her firstborn son: and he called His Name
