Matthew 1
18 Ref Now the birth of Jesus Christ was like this; for after his mother, Mary, was engaged to Joseph, before they came together, she was found pregnant by the Holy Spirit.
19 Ref Joseph, her husband, being a righteous man, and not willing to make her a public example, intended to put her away secretly.
20 Ref But when he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, 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.
