Isaiah must be kept in context and with knowledge of history and context within the historical events it's speaking of:
G-d promised Ahaz His help (Isaiah 7:4--9) but suggested that he nevertheless ask for a sign of the
L-rd's protection:
Isaiah 7:10-11
And the L--rd spoke again to Ahaz, saying: “Ask a sign of the L-rd, your G-d....”
Read the context:
In Isaiah 7:14 this mere SIGN of a child being born to a YOUNG Woman (almah), was explicitely for Ahaz in HIS day 600 years prior to the Jesus Character. Nowhere would this sign do Ahaz any good 600 years after he’s dead.
Thus the FULL context must be discussed. Reading prior verses we notice this is About Ahaz in his day and age and thus 7:14 in context with later verses shows it’s about Ahaz’s son (Hezekiah) which was born and eventually became King and having G-d with him meant supporting his Kingdom of Judah.
King Hezekiah and his kingdom (Judah), were looming on an eventual invasion by the Assyrian army.
Which is in the context of Isaiah 8:7-8.
With the often abuse and mistaken use of Isaiah 9:5-6
we see: "For to us a child has been born, (King Hezekiah)
to us a son has been given, and the government is upon his shoulder"
(Hezekiah inherited his father Ahaz’s throne. Hence, the verse states that "the government *is*upon his shoulder," in the present, not that it "will be" in the future.)
"and he called his name “Wonderful in Counsel" or ‘Messenger (angel) of great counsel’ depending on the translation.
G-d's counsel to Hezekiah was quite prophetic in nature and he as King became a great counsel (father figure).
"Mighty G-d, the Everlasting Father, Prince of Peace.” "
With G-d’s Might he prevailed against the Assyrians and also prolonged his life to be a great father (great counsel) to the kingdom of Judah.
Also Hezekiah's name imply attributes of G-d
The last part about "prince of peace" (which never fit Jesus or his Church) is in regards to peace enjoyed by the kingdom after the defeat of the Assyrian army.
**Note These verses in Isaiah 9:5-6 also mirrors labels given Archangel Michael as Father of the Hosts, the main messenger, and Head of the counsel which is why JW’s say 9:6 is about Michael, and rightfully so since The Hezekiah Apochryphon (4Q470) Shows Hezekiah taking counsel through conversing with the head Counsel Archangel Michael who made a covenant with Hezekiah. So these verses in context are historical events and yet it’s true they do carry deeper Messianic revelation but it is pointing to the Shiloh Michael and not the false prophet Jesus.
Don't you love how the scrolls clear that up for us?
It's as though they are the scrolls mentioned in Daniel and Revelation.
