Reply To: Dvar Torah Va’Eschanan — Reasons for Rest.

So according to the RMA above both are true. Zachor for talmidei chachomim as they learn and don’t work the whole week and available to guard shabbos and rest anyway. So they must honor shabbos by eating and drinking. Shamor for baalei batim who are busy the whole week emphasizing to stop working on shabbos and set time for learning.
