John Gill Commentary Exodus 23:10

"And six years thou shalt sow thy land, and shalt gather in the increase thereof:" — Exodus 23:10 (ASV)

And six years you shall sow your land ,
The land of Canaan, given to their ancestors and to them, and which they were now going to inherit; and when they came into it they were to plant it with vines and olives; or rather, these being ready planted, they were to prune and dress them; and they were to till their land, and plough it, and sow it with various sorts of grain, for six years running, from the time of their possession of it:

and shall gather in the fruits thereof ;
corn and wine, and oil, into their own garners, treasuries, and cellars, as their own property, to dispose of as they pleased for their own use and profit.
