'Wheat' in the Bible

And Ornan turneth back, and seeth the messenger, and his four sons are with him, hiding themselves, and Ornan is threshing wheat.

And Ornan saith unto David, 'Take to thee -- and my lord the king doth that which is good in his eyes: see, I have given the oxen for burnt-offerings, and the threshing instruments for wood, and the wheat for a present; the whole I have given.'
