Jerome, on Matt 1:22

“Now all this was done that it might be fulfilled which the Lord spoke by the prophet, saying:”

“(ubi sup.) It should be known, that the Hebrews believe this prophecy to refer to Ezekias the son of Ahaz, because in his reign Samaria was taken; but this cannot be established. Ahaz son of Jotham reigned over Judæa and Jerusalem sixteen years, and was succeeded by his son Ezekias, who was twenty-three years old, and reigned over Judæa and Jerusalem twenty-nine years; how then can a prophecy prophesied in the first year of Ahaz refer to the conception and birth of Ezekias, when he was already nine years of age? Unless perhaps the sixth year of the reign of Ezekias, in which Samaria was taken, they think is here called his infancy, that is, the infancy of his reign, not of his age; which even a fool must see to be hard and forced. A certain one of our interpreters contends, that the Prophet Isaiah had two sons, Jashub and Emmanuel; and that Emmanuel was born of his wife the Prophetess as a type of the Lord and Saviour. But this is a fabulous tale.”
