Matthew 1 is outside of your Scripture?
Matthew 1: 22 All this took place to fulfill what the Lord had said through the prophet: 23 11 "Behold, the virgin shall be with child and bear a son, and they shall name him Emmanuel," which means "God is with us." 24 When Joseph awoke, he did as the angel of the Lord had commanded him and took his wife into his home. 25 He had no relations with her until she bore a son, 12 and he named him Jesus.
Matthew 1:22 refers to Isaiah, which originally refered to the birth of King Hezikiah.
If you get a good old testament translation you can get a sense that the author of matthew overreached just a tad.
