'Grain Offering' in the Bible

And Ornan said to David, "Take [it] to yourself; let my lord the king do what [is] good in his eyes. See, I give the cattle for the burnt offerings and threshing sledges for the wood and wheat for the grain offering--I give [it] all."

and with the rows of bread, the flour, the grain offering, the wafers of unleavened bread, the baked offering, the offering mixed with oil, and for all the amounts and measurements.
