Isaiah 7:10-16 (NIVUK)
10 Again the Lord spoke to Ahaz, 11 ‘Ask the Lord your God for a sign, whether in the deepest depths or in the highest heights.’
12 But Ahaz said, ‘I will not ask; I will not put the Lord to the test.’
13 Then Isaiah said, ‘Hear now, you house of David! Is it not enough to try the patience of humans? Will you try the patience of my God also? 14 Therefore the Lord himself will give you a sign: the virgin will conceive and give birth to a son, and will call him Immanuel. 15 He will be eating curds and honey when he knows enough to reject the wrong and choose the right, 16 for before the boy knows enough to reject the wrong and choose the right, the land of the two kings you dread will be laid waste.
Matthew 1:18-25 (NIVUK)
Joseph accepts Jesus as his son
18 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. 19 Because Joseph her husband was faithful to the law, and yet 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, 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’ (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.
