20But when he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, you son of David, don`t be afraid to take to yourself Mary, your wife, for that which is conceived in her is of the Holy Spirit. 21She shall bring forth a son. You shall call his name JESUS, for it is he who shall save his people from their sins."
