Matthew 1:20-23

20But 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.

21She will give birth to a son, and you are to give him the name Jesus, Jesus is the Greek form of Joshua, which means the Lord saves. because he will save his people from their sins.” 22All 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” Isaiah 7:14 (which means “God with us”).
