Leviticus 23:14

You must not eat bread, or roasted grain, or fresh grain, until this same day, until you have brought the offering of your God. This is a statute forever throughout your generations in all your dwellings.

And ye shall eat neither bread, nor parched corn, nor green ears, until the selfsame day that ye have brought an offering unto your God: it shall be a statute for ever throughout your generations in all your dwellings.
