Matthew 1:22-25

All this happened to bring about what the Lord had said through the prophet: “The virgin will be pregnant. She will have a son, and they will name him Immanuel,” which means “God is with us.” When Joseph woke up, he did what the Lord’s angel had told him to do. Joseph took Mary as his wife, but he did not have sexual relations with her until she gave birth to the son. And Joseph named him Jesus.
