Nissan Dovid Dubov, in The Eternal Nature of the Torah, says:
The Talmud teaches that mitzvahs will be nullified in the Messianic age. How do we reconcile this with Judaism’s cardinal principal that Torah is eternal and mitzvahs don’t change?
However, the website HaDavar argues that the mitzvot are not eternal.
I actually saw a verse in Torah saying that Torah is eternal. That is, all the 613 commandments must be done. I forget the verse.
Can anyone please just point the verse because I couldn't find it.
