Looking at Ex 23:11, do you see a 7 year crop rotation with 7th year fallow as the equivalent of a 7th year Sabbath?
No. This was a multifaceted plan to maintain logistical stores of food in remote locations, train a national militia, maintain a vital pastoral cohort, and to train and empower the poor. All of that was incorporated in that one verse. It is amazing. In fact, it is the key to understanding much of the Sermon on the Mount and the parables of Matthew 25.
