Leviticus 25:20-22

MSB(i) 20 Now you may wonder, ‘What will we eat in the seventh year if we do not sow or gather our produce?’ 21 But I will send My blessing upon you in the sixth year, so that the land will yield a crop sufficient for three years. 22 While you are sowing in the eighth year, you will be eating from the previous harvest, until the ninth year’s harvest comes in.
