What the Bible says about Agricultural Laws
(From Forerunner Commentary)

Leviticus 25:2-5 The land sabbath gives cultivated fields a chance both to rest and return vital nutrients to the soil, allowing it to produce bountifully for an indefinite time. This law enhances the quality of the produce, which leads to healthier people and livestock. Richard T.
