Leviticus 25:18-23

25:18 You must obey my statutes and my regulations; you must be sure to keep them so that you may live securely in the land.

25:19 “‘The land will give its fruit and you may eat until you are satisfied, and you may live securely in the land. 25:20 If you say, ‘What will we eat in the seventh year if we do not sow and gather our produce?’ 25:21 I will command my blessing for you in the sixth year so that it may yield the produce for three years, 25:22 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. 25:23 The land must not be sold without reclaim because the land belongs to me, for you are foreigners and residents with me.
