Marcello Trebitsch asked:
Dear rabbi,
When the gemarah gives different answers as to why we need less then 20 amos, why do we not say simply that since it is like a mavoi and a mavoi can only be 20 amos here too
Best Regards,
Marcello Trebitsch
The Kollel replies:
The entire concept of a Korah in a Mavoy, and certainly its being less than twenty Amos, is mid'Rabanan. We definitely cannot find the source of a Halachah mid'Oraisa from a Halachah mid'Rabanan.
All the best,
Yaakov Montrose
