A furrow is an opening, ridge, or line in soil made by a plough. Biblical fields were left in furrows after seed was sown and the softened earth was turned over.
Furrows occur in descriptions of cultivated fields and are also used figuratively for oppression or the marked consequences of wrongdoing.
The ancient Syrian farmer ploughed after showers softened the ground and generally left the soil in furrows rather than harrowing it into the finely pulverized surface familiar in modern farming.
