Leviticus 25:5

And thou shalt not gather the spontaneous produce of thy field, and thou shalt not gather fully the grapes of thy dedication: it shall be a year of rest to the land.

That 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.

What grows of itself in your harvest you shall not reap, and you shall not gather the grapes of your undressed vine. It shall be a year of solemn rest for the land.
