Exodus 23:10-11 King James Version (KJV)
10 And six years thou shalt sow thy land, and shalt gather in the fruits thereof:
11 But the seventh year thou shalt let it rest and lie still; that the poor of thy people may eat: and what they leave the beasts of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thy oliveyard.
Leviticus 25:20-22 King James Version (KJV)
20 And if ye shall say, What shall we eat the seventh year? behold, we shall not sow, nor gather in our increase:
21 Then I will command my blessing upon you in the sixth year, and it shall bring forth fruit for three years.
22 And ye shall sow the eighth year, and eat yet of old fruit until the ninth year; until her fruits come in ye shall eat of the old store.
