Leviticus 25
2 Ref 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 Ref Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruits thereof;
4 Ref 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.
