'Wheat' in the Bible

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

The prophet that hath a dream, let him tell a dream; and he that hath my word, let him speak my word faithfully. What is the straw to the wheat? saith Jehovah.

But ten men were found among them that said unto Ishmael, Slay us not; for we have stores hidden in the field, of wheat, and of barley, and of oil, and of honey. So he forbare, and slew them not among their brethren.
