'Wheat' in the Bible

And Ornan turned back, and saw the angel; and his four sons that were with him hid themselves. Now Ornan was threshing wheat.

And Ornan said unto David, Take it to thee, and let my lord the king do that which is good in his eyes: lo, I give thee the oxen for burnt-offerings, and the threshing instruments for wood, and the wheat for the meal-offering; I give it all.
