The Hebrew word qetsach refers to black cumin (Nigella sativa), an aromatic herb cultivated in the ancient Near East for its seeds, used in cooking and medicine. It appears in Isaiah 28 in an agricultural parable about the wisdom of farming.
Isaiah 28:25β29 contains a remarkable agricultural parable in which God teaches through the wisdom of farming: different crops require different treatment β dill is not threshed with a threshing sledge, cumin (qetsach) is beaten with a stick, wheat with a wheel. The passage concludes: 'This also comes from the LORD of hosts; he is wonderful in counsel and excellent in wisdom.' The theological point is profound: God deals with each person and each nation according to their specific nature and need. His 'threshing' β His discipline and judgment β is not uniform brute force but calibrated wisdom. The ordinary agricultural knowledge of planting qetsach becomes a window into the character of God.
