'Wheat' in the Bible

They have sown wheat, and they reap thorns; they have put themselves to pain, and do not profit. Be ye therefore ashamed of your revenues, because of the fierce anger of Jehovah.

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

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