'Wheat' in the Bible

“They have sown wheat and have reaped thorns,They have strained themselves to no profit.But be ashamed of your harvestBecause of the fierce anger of the Lord.”

But ten men who were found among them said to Ishmael, “Do not put us to death; for we have stores of wheat, barley, oil and honey hidden in the field.” So he refrained and did not put them to death along with their companions.
