'Caraway' in the Bible

Once he has leveled its surface, does he not scatter the seed of the caraway plant, sow the seed of the cumin plant, and plant the wheat, barley, and grain in their designated places?

Certainly caraway seed is not threshed with a sledge, nor is the wheel of a cart rolled over cumin seed. Certainly caraway seed is beaten with a stick, and cumin seed with a flail.
