LEVITICUS 25:2-5

²Speak 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 the LORD.

³Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruits thereof;

⁴but in the seventh year shall be a sabbath of solemn rest for the land, a sabbath unto the LORD: thou shalt neither sow thy field, nor prune thy vineyard.

⁵That 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.
