Matthew 1:18, 23-25

This is how Jesus the Messiah was born. His mother, Mary, was engaged to be married to Joseph. But before the marriage took place, while she was still a virgin, she became pregnant through the power of the Holy Spirit.

“Look! The virgin will conceive a child! She will give birth to a son, and they will call him Immanuel, which means ‘God is with us.’” When Joseph woke up, he did as the angel of the Lord commanded and took Mary as his wife. But he did not have sexual relations with her until her son was born. And Joseph named him Jesus.
