Leviticus 25:3-5

Amplified Bible

³ For six years you shall sow your field, and for six years you shall prune your vineyard and gather in its crop. ⁴ But in the seventh year there shall be a Sabbath of rest for the land, a Sabbath to the Lord; you shall not sow [seed in] your field nor prune your vineyard. ⁵ Whatever reseeds itself (uncultivated) in your harvest you shall not reap, nor shall you gather the grapes from your uncultivated vine, it shall be a year of sabbatical rest for the land.
