Leviticus 25:18-22 - The Problem Of The Seventh Year
18 You must obey my statutes and my regulations; you must be sure to keep them so that you may live securely in the land. 19 "'The land will give its fruit and you may eat until you are satisfied, and you may live securely in the land. 20 If you say, 'What will we eat in the seventh year if we do not sow and gather our produce?' 21 I will command my blessing for you in the sixth year so that it may yield the produce for three years, 22 and you may sow the eighth year and eat from that sixth year's produce -- old produce. Until you bring in the ninth year's produce, you may eat old produce.
