Leviticus 25:18-22

‘So you shall observe My statutes and keep My judgments, and perform them; and you will dwell in the land in safety. Then the land will yield its fruit, and you will eat your fill, and dwell there in safety. ‘And if you say, “What shall we eat in the seventh year, since we shall not sow nor gather in our produce?” Then I will command My blessing on you in the sixth year, and it will bring forth produce enough for three years. And 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.
