Fallow-ground: The expression, "Break up your fallow ground"
(Hosea 10:12; Jeremiah 4:3) means,
"Do not sow your seed among thorns", i.e., break off all your evil
habits; clear your hearts of weeds, in order that they may be
prepared for the seed of righteousness. Land was allowed to lie
fallow that it might become more fruitful; but when in this
condition, it soon became overgrown with thorns and weeds. The
cultivator of the soil was careful to "break up" his fallow ground,
i.e., to clear the field of weeds, before sowing seed in it. The Song of Solomon says
the prophet, "Break off your evil ways, repent of your sins, cease to
do evil, and then the good seed of the word will have room to grow
and bear fruit."
