'Wheat' in the Bible

They have sown wheat, and have reaped thorns; they have put themselves to pain, and profit nothing: and you shall be ashamed of your fruits, because of the fierce anger of Yahweh.

The prophet who has a dream, let him tell a dream; and he who has my word, let him speak my word faithfully. What is the straw to the wheat? says Yahweh.

But ten men were found among those who said to Ishmael, Don't kill us; for we have stores hidden in the field, of wheat, and of barley, and of oil, and of honey. So he stopped, and didn't kill them among their brothers.
