Leviticus 23:14

And ye shall eat neither bread, nor parched corn, roasted at the fire, nor green ears, of the new harvest, until the selfsame day that ye have brought an offering unto your god; it shall be a statute forever throughout your generations in all your dwellings, in the land of Canaan, as long as the Levitical priesthood endured. The use of the new grain for food in any form whatever before the ceremony of waving on the sixteenth of Nisan was absolutely forbidden. All our possessions, all the members of our bodies, should be consecrated to the Lord for diligence in good works.
