- R. Simlai in Makkot 23b expounds that there are 613 mitzvot – 248 positive commandments and 365 negative commandments.
- Rambam tried very hard to calculate the exact 613 mitzvot, and surpassed all his predecessors in this regard, but there are still many issues with what he did.
- The issues with Rambam's counting are not due to any flaw of Rambam's; rather the number 613 was not really precise, and R. Simlai didn't care becacausebecause he wanted to make an exposition with the significance of the number 613.
- Therefore, when counting the mitzvot, we should ignore R. Simlai's statement, and only count based on the actual truth.
- Furthermore, even if R. Simlai was being precise, we don't have to contend with his number because if our analysis of the Talmud results in a higher count then it would simply be a dispute and we would reject R. Simlai as the minority view.
