Leviticus 25:20–22

20 And if you say, n‘What shall we eat in the seventh year, if owe may not sow or gather in our crop?’ 21 I will pcommand my blessing on you in the sixth year, so that it will produce a crop sufficient for three years. 22 qWhen you sow in the eighth year, you will be eating some of rthe old crop; you shall eat the old until the ninth year, when its crop arrives.
