Leviticus 25:3-5

The Sabbath Year

³ For six years you shall sow your field, and for six years you shall prune your vineyard and gather in its fruits, ⁴ but in the seventh year there shall be a Sabbath of solemn rest for the land, a Sabbath to the Lord. You shall not sow your field or prune your vineyard. ⁵ _y You shall not reap what grows of itself in your harvest, or gather the grapes of your undressed vine. It shall be a year of solemn rest for the land.
