Jeremiah 31

[Robert]

Thanks Robert.

So it seems pretty clear to me Jeremiah is not talking about anything that has to do with the Christian bible.

I may tend to be over-detailed and if so, sorry; but it should be clear that the Jewish Scriptures do not contain any Christological prophesies. 
There are many claimed by Christian missionaries, all such claims fake, and every such claim aimed at Jews who both lack knowledge about their own religion and also tend to be vulnerable in other ways.
