Leviticus 25:19-22

19And the land shall yield its fruit, and ye shall eat and be satisfied, and dwell therein securely.

20And if ye say, What shall we eat in the seventh year? behold, we may not sow, nor gather in our produce;

21then I will command my blessing upon you in the sixth year, that it may bring forth produce for three years;

22and ye shall sow in the eighth year, and ye shall eat of the old fruit until the ninth year; until her produce come in, ye shall eat the old.
