Leviticus 25:5

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 the grapes of your undressed vine you shall not gather. It shall be a year of solemn rest for the land.

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.

the spontaneous growth of thy harvest thou dost not reap, and the grapes of thy separated thing thou dost not gather, a year of rest it is to the land.

You are not to reap the aftergrowth of your harvest or gather the grapes of your untended vines. The land must have a year of complete rest.
