'Fallow' in the Bible

But in the seventh year you must let it lie fallow and leave it alone so that the poor of your people may eat, and what they leave any animal in the field may eat; you must do likewise with your vineyard and your olive grove.

We will not buy on the Sabbath or on a holy day from the neighboring peoples who bring their wares and all kinds of grain to sell on the Sabbath day. We will let the fields lie fallow every seventh year, and we will cancel every loan.
