Matthew 1:21-23, 25

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.” All this took place to fulfill what the Lord had said through the prophet: “The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”).

But he did not consummate their marriage until she gave birth to a son. And he gave him the name Jesus.
