Matthew 1:18-25  New International Version - UK

Joseph accepts Jesus as his son

¹⁸ This is how the birth of Jesus the Messiah came about^[a]: 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. ¹⁹ Because Joseph her husband was faithful to the law, and yet^[b] did not want to expose her to public disgrace, he had in mind to divorce her quietly.

²⁰ But after he had considered 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 home as your wife, because what is conceived in her is from the Holy Spirit. ²¹ She will give birth to a son, and you are to give him the name Jesus,^[c] because he will save his people from their sins.’

²² All this took place to fulfil what the Lord had said through the prophet: ²³ ‘The virgin will conceive and give birth to a son, and they will call him Immanuel’^[d] (which means ‘God with us’).

²⁴ When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. ²⁵ But he did not consummate their marriage until she gave birth to a son. And he gave him the name Jesus.
