Leviticus 25:19-22

19Then the land will yield its fruit, and you will eat your fill, and dwell there in safety.

20‘And if you say, “What shall we eat in the seventh year, since we shall not sow nor gather in our produce?”

21Then I will command My blessing on you in the sixth year, and it will bring forth produce enough for three years.

22And you shall sow in the eighth year, and eat old produce until the ninth year; until its produce comes in, you shall eat of the old harvest.
