'Uncultivated' in the Bible

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.

That fiftieth year shall be a Jubilee for you; you shall not sow [seed], nor reap what reseeds itself, nor gather the grapes of the uncultivated vines.

The pastures of the wilderness drip [with dew],And the hills are encircled with joy.

A senseless man [in his crude and uncultivated state] knows nothing,Nor does a [self-righteous] fool understand this:

For this is what the Lord says to the men of Judah and to Jerusalem,“Plow your uncultivated ground [for a season],And do not sow among thorns.

Sow with a view to righteousness [that righteousness, like seed, may germinate];Reap in accordance with mercy and lovingkindness.Break up your uncultivated ground,For it is time to seek and search diligently for the Lord [and to long for His blessing]Until He comes to rain righteousness and His gift of salvation on you.

Our people must learn to do good deeds to meet necessary demands [whatever the occasion may require], so that they will not be unproductive.
