Six years you shall sow your land and gather in its yield; but in the seventh you shall let it rest and lie fallow. Let the needy among your people eat of it, and what they leave let the wild beasts eat. You shall do the same with your vineyards and your olive groves.
(20) And should you ask, “What are we to eat in the seventh year, if we may neither sow nor gather in our crops?”(21) I will ordain My blessing for you in the sixth year, so that it shall yield a crop sufficient for three years.
It is a positive commandment to annul [ownership of] everything that comes out of the ground in the seventh year as it says "and in the seventh [year], annul it and forsake it" and anyone who locks up his vineyard or fences in his field in the seventh year has violated a positive commandment, and similarly someone who harvest all his fruits and brings them inside. Rather everything should be seen as ownerless and everyone has equal claim as it says " and the destitute of your people will eat it." [The owner] may bring in small amounts the way one does from ownerless property e.g. five pitchers of oil or fifteen of wine and if he brought in more it is permitted.
