16: The Angel's message
But as Joseph was thinking about this, an angel of the Lord appeared to him in a dream. The angel said, “Joseph, son of David, don't be afraid to take Mary home as your wife. The baby inside her is from the Holy Spirit.
She is going to have a son. You must give him the name Jesus. That is because he will save his people from their sins.”
Matthew 1:20-21
