Leviticus 25:3-7

Six years you shall sow your field, and six years you shall prune your vineyard, and gather its fruit; but in the seventh year there shall be a sabbath of solemn rest for the land, a sabbath to the LORD. You shall neither sow your field nor prune your vineyard. What grows of its own accord of your harvest you shall not reap, nor gather the grapes of your untended vine, for it is a year of rest for the land. And the sabbath produce of the land shall be food for you: for you, your male and female servants, your hired man, and the stranger who dwells with you, for your livestock and the beasts that are in your land—all its produce shall be for food.
