Matthew 1:19-24 NIV

[19] Because Joseph her husband was faithful to the law, and yet did not want to expose her to public disgrace, he had in mind to divorce her quietly. [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. [21] She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.” [22] All this took place to fulfill what the Lord had said through the prophet: [23] “The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”). [24] When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife.
