'Fallow' in the Bible

but the seventh year thou shalt let it rest and lie fallow; that the poor of thy people may eat: and what they leave the beast of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thy oliveyard.

For thus saith Jehovah to the men of Judah and to Jerusalem, Break up your fallow ground, and sow not among thorns.

Sow to yourselves in righteousness, reap according to kindness; break up your fallow ground; for it is time to seek Jehovah, till he come and rain righteousness upon you.
