“Given that all of them learn hebrew since, like, five years old or something, I have doubts about that going to be a convincing argument.”
Seems they forget it often when the topic comes to anything mildly connected to Jesus Christ.
Still, probably nobody (and specially not Jews, let alone Israeli Jews that speak it since ever) is going to believe *your* hebrew is better than the Torah scholars’. Unless you’re kind of like a prodigy language whiz, and even then just maybe.
The question is “Why Did the Jews Reject Christianity?”, after all. That’s just not an argument Jews will take.
