Matthew 1:18, 23-25

This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit.

“The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”). When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. But he did not consummate their marriage until she gave birth to a son. And he gave him the name Jesus.
