Asalam ul laykum, In regards to Isaiah 9:6 brother osama i believe u have something there. I was trying to understand the context of the verse and i ran into this.
Isaiah 10:
The Remnant of Israel
20 In that day the remnant of Israel,
the survivors of Jacob,
will no longer rely on him
who struck them down
but will truly rely on the Lord,
the Holy One of Israel.
21 A remnant will return, a remnant of Jacob
will return to the Mighty God.
22 Though your people be like the sand by the sea, Israel,
only a remnant will return.
Destruction has been decreed,
overwhelming and righteous.
23 The Lord, the Lord Almighty, will carry out
the destruction decreed upon the whole land.
24 Therefore this is what the Lord, the Lord Almighty, says:
“My people who live in Zion,
do not be afraid of the Assyrians,
who beat you with a rod
and lift up a club against you, as Egypt did.
With context of both isaiah 9 and 10, with both chapters i can see a reason why the jews at that time could of had made that serious mistake. But i wonder when did they correct this mistake, since today they do not regard ezra as son of god.
