Leviticus 25
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.
5 Ref 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.
