Matthew 1:20-25

When he had contemplated 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 as your wife, because the child conceived in her is from the Holy Spirit. She will give birth to a son and you will name him Jesus, because he will save his people from their sins.” This all happened so that what was spoken by the Lord through the prophet would be fulfilled: “ Look! The virgin will conceive and bear a son, and they will call him Emmanuel ,” which means “God with us.” When Joseph awoke from sleep he did what the angel of the Lord told him. He took his wife, but did not have marital relations with her until she gave birth to a son, whom he named Jesus.
