Question re Dovid protected due to his Torah. And so Doeg & Achitopel were not successful. My question is why were not Doeg & Achitopel protected due to THEIR Torah learning?
The Gemara in Sanhedrin 106b states that Doeg's Torah was "m'Safah u'Lchutz" and therefore it was not able to protect him. The Gemara also says that David asked that Doeg forget his Torah so he then could be taken.
