'Wheat' in the Bible

They have sown wheat and they have reaped thorns. They are exhausted, they do not profit. And they will be ashamed of your produce, because of {the burning anger} of Yahweh."

The prophet who [has] with him a dream, let him tell [the] dream. But [the prophet] who [has] my word with him, let him speak my word faithfully. {What is straw compared to wheat}?" {declares} Yahweh.

But ten men were found among them, and they said to Ishmael, "You must not kill us, for {we have} hidden treasures in the field, wheat, and barley, and oil, and honey. So he refrained and he did not kill them in the midst of their fellow countrymen.
