Matthew 1:20
King James Version
“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.”
Context
17So all the generations from Abraham to David fourteen generations; and from David until the carrying away into Babylon fourteen generations; and from the carrying away into Babylon unto Christ fourteen generations.
18Now 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.
19Then Joseph her husband, being a just and not willing to make her a publick example, was minded to put her away privily.
20But 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.
21And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
22Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,
23Behold, 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.
