" Jesus is never mentioned by name or title(son of god, messiah etc). Why didnt Moses simply write Jesus son of God here ? The answer is of course Jesus is a new made up invention that only appears in the NT, there is no Jesus in the OT. If you dont blieve me ask any Rabbi."
Think about it. If Moses had said that the person would be named Jesus and gave more specifics, then everyone would name their kids Jesus and arrange the specifics.
Yes, that was how to identify false prophets in that many would claim to be the messiah and how to find the real one and what to do with him.
But the issue and problem never is who Jesus was just as it is not about whether God created everything. The issues is what Jesus and God will do in the future and when.
