Prophecy may not be a major factor in the way many moderns conceive of the Christmas story. But it was clearly a vital strain for both Luke and Matthew, who each took up that chorus and peppered their Nativity accounts with allusions and references to prophecies fulfilled by the birth of Jesus.

Both Matthew and Luke fill their Nativity account with prophecies from the Old Testament. Matthew does it editorially while Luke uses people to bring in the prophecies.
