'Fallow' in the Bible

but the seventh year you shall let it rest and lie fallow, that the poor of your people may eat; and what they leave the animal of the field shall eat. In the same way, you shall deal with your vineyard and with your olive grove.

For thus says Yahweh to the men of Judah and to Jerusalem, "Break up your fallow ground, and don't sow among thorns.

Sow to yourselves in righteousness, reap according to kindness. Break up your fallow ground; for it is time to seek Yahweh, until he comes and rains righteousness on you.
