Leviticus 25:19-22

19Then the land will yield its fruit, so that you can eat, be satisfied, and live securely in the land.

20If you wonder, ‘What will we eat in the seventh year if we don’t sow or gather our produce?’

21I will appoint my blessing for you in the sixth year, so that it will produce a crop sufficient for three years.

22When you sow in the eighth year, you will be eating from the previous harvest. You will be eating this until the ninth year when its harvest comes in.
