Leviticus 25:3 KJV

1And the LORD spake unto Moses in mount Sinai, saying,

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 fruit thereof;

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

5That which groweth of its own accord of thy harvest thou shalt not reap, neither gather the grapes of thy vine undressed: for it is a year of rest unto the land.
