Those scriptures dont have anything to do with Jesus. Isaiah 9
And we will only know who the messiah is, AFTER he has accomplished ALL his messianic tasks, not before, not half way, no down payment, after. Otherwise, people will believe in false messiahs.
R. Tovia Singer, as well as other experts in this matter, say that the real messiah will be accepted by most non-Jews with relative ease. To me, however, it seems Christian eschatology has programmed Christians to launch suicidal attacks on the real messiah, viewing him as the anti-Christ. America seems likely to be the real messiah’s biggest opponent.
