Matthew 1:18; Matthew 1:20

18 This is how the birth of Jesus the Messiah came about : His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit.

20 But after he had considered this, an angel of the Lord appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit.
