Leviticus 25:1-6

1 ¶ And Jehovah spake unto Moses in mount Sinai, saying, 2  Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto Jehovah.  3  Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruits thereof;  4  but in the seventh year shall be a sabbath of solemn rest for the land, a sabbath unto Jehovah: thou shalt neither sow thy field, nor prune thy vineyard.  5  That which groweth of itself of thy harvest thou shalt not reap, and the grapes of thy undressed vine thou shalt not gather: it shall be a year of solemn rest for the land.  6  And the sabbath of the land shall be for food for you; for thee, and for thy servant and for thy maid, and for thy hired servant and for thy stranger, who sojourn with thee.
