Matthew 1:18-21

Now the birth of Jesus Christ was as follows: …His mother Mary was found with child of the Holy Spirit..Joseph her husband,…was minded to put her away secretly…But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, “…, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit…she will bring forth a Son, and you shall call His name JESUS, for He will save His people from their sins.”
