When Jesus was choosing his twelve apostles, an unlikely choice was Matthew.  He was hated by the Jews because he had become a tax collector--for the Roman government.   The tax collectors were notorious for taking more than the Romans demanded to line their own pockets.

But when Jesus passed by, he looked at Matthew, and chose him.  Mark 2:14  "And as he passed by, he saw Levi (Matthew) the son of Alphaeus sitting at the receipt of custom, and said unto him, Follow me. And he arose and followed him. 

Jesus saw something in Matthew that others didn't.  Because of that, we have a wonderful story that Matthew wrote about Jesus that gives us at least nine incidents that Mark, Luke and John didn't.  We only have  these four accounts of the life of Jesus.  Luke wrote his account by interviewing people who knew Jesus personally.  Mark was from Jerusalem, but was usually identified as a friend of Paul, not Jesus.  Matthew wrote to the Jews.  His desire was to prove that Jesus was the Jewish Messiah.

 In the book of Isaiah it is prophesied (7:14) "Therefore the Lord himself shall give you a sign...a virgin shall conceive, and bear a son, and shall call his name Immanuel."  (Which is one name for God.)  Isaiah continues in verse 16 "...the child shall know to refuse the evil and choose the good..."
  
Number 1.  The first thing that Matthew shares with us that is found no where else, is Joseph's dream. Joseph was worried about Mary being pregnant out of wedlock.  Matt. 1:20-24 "...while he thought on these things, behold the angel of the Lord appeared to him...saying...fear not to take...Mary to be your wife.  That which is conceived in her is of the Holy Ghost...she shall have a son, and they shall call his name Jesus: for he shall save his people from their sins.  Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet (Isaiah)..."

And then Matthew quotes the verse above from Isaiah 7:14.  "They shall call his name Emmanuel, which being interpreted is God with us."  Prophesy fulfilled.
