Exactly the kind of lame retort I’d expect from you.
Newsflash: Not only was Jesus a Jew, all the apostles were Jews, & Paul studied under Gamaliel—a leading rabbi.
The New Testament wasn't written by gentiles; it was written by Jews, about a Jew, for the world.
And Jesus knew Isaiah 53 inside & out—He knew He was the Suffering Servant, & He knew His own people would reject Him, just as YOU continue to do to this day.
When a pox falls on your house, who you gonna blame?
